Zap Screwlok MECHANICAL SPLICES

INTRODUCTION AND OVERVIEW

Creating structural continuity within the reinforcement system on construction projects can be critical. High performance mechanical splices are often essential in helping safeguard against the unexpected and / or catastrophic effects of stress overload.

Type 1 Mechanical Splices According to the ACI Building Code and Commentary, the maximum reinforcement stress used in design under the code is the specified yield strength. To ensure sufficient strength in splices so that yielding can be achieved in a member, and thus brittle failure avoided, mechanical connections should develop at least 125% of the specified yield. The 25% increase above the specified yield strength was selected [by ACI] as both an adequate minimum for safety and a practical maximum for economy.

The SL series of the Zap Screwlok mechanical splice system complies with the Type 1 full mechanical splice requirement of ACI 318 for 125% x specified yield, when used to connect standard uncoated bars that conform to ASTM A615 Grade 60 or ASTM A 706.

Type 2 Mechanical Splices The Type 2 series of the Zap Screwlok mechanical splice system complies with the higher performance definitions for Type 2 mechanical splices. Applications for Type 2 mechanical splices include structures that may have to withstand the effects of seismic loading or high wind loading, impact and blast, or other dynamic condition.

Zap Screwlok is the system of choice for highly congested areas, where it might be impractical or impossible to install a threaded-type coupler or a similar device. The Zap Screwlok System is also convenient for use on the project site in case of unplanned splicing or as a supplemental splicing system.

A series of screws, when tightened, embed into the bars while the high tightening force causes the rebar profile to interlock with a wedge in the coupler body. Rebar ends may be sheared, flame-cut or sawed.

MECHANICAL SPLICES and LAP SPLICES

ITEM COMMENTS

1 DEVELOPMENT STRENGTH

Lap splices, by nature, can only be designed to develop 100% x specified yield. Mechanical Splices, as a minimum, are design to develop 125% x specified yield.

2 DESIGN VARIABLES

ACI 318-05 rules for lap splice designs are complicated because there are twelve (12) factors or more that affect the tensile development length. The performance of a mechanical splice is independent of the surrounding concrete; independent of the bar spacing, the concrete cover and the splice location.

3 CONCRETE ELEMENT DESIGN

Minimizing structural element size is often an objective of architects and engineers. Building code requirements for lap splices can compromise this objective. By butting bars end-to-end and using a mechanical butt splice, space can be saved.

4 DYNAMIC OVERLOAD

Cyclic loading, such as that induced into the reinforcing system during high wind, seismic activity or other dynamic condition, can result in the failure of lap splices. Performance depends upon the quality and compaction of the surrounding concrete.

5 SEISMIC PROVISIONS

The use of lap spices in seismic zones generally is disallowed. Lap splices can not withstand inelastic strain excursions because the ensuing destruction of the bond with the concrete will result in the ineffectiveness of the lap. As part of seismic qualification protocol(s), mechanical splices are cyclically loaded.

6 CONGESTION By using mechanical splices, lap bars are eliminated and rebar congestion is minimized. This results in improved space for pouring and vibrating thereby enhancing concrete consolidation, lowering concrete placement costs and improving in-place concrete quality.

7 SPLITTING When a tensile load is applied to a lapped bar embedded in concrete, a complex stress pattern is generated within the concrete between and around the lapped bar. There is a resulting tendency for the bar to cause splitting of the concrete cover in the plane of the lap, especially under severe loading conditions.

8 SPALLING If spalling of concrete cover occurs around the lapped bar by fire, corrosion or another mechanism, the effectiveness of the lap is compromised because the performance of a lap is 100% dependent upon the concrete that surrounds it.

In these cases, the use of mechanical splices has clear advantages because load transfer between the rebars is independent of the concrete. This is verified by in-air testing.

WELDED JOINTS

In the event that there are requirements to connect reinforcing bars to structural steel, the use of a STRUCTURAL CONNECTOR is recommended. For information on different types of Structural Connectors that are available, please contact BarSplice Products, Inc.

The use of bar-to-bar welded joints must always be approached with due caution. ASTM A 706 bars or equivalent must be used to achieve consistent performance. Welding directly to ASTM A615 is generally not recommended.

ACI 318-05 has no provisions for Type 2 performance-based welds.

Welded rebar joints are not permitted by ACI 318-05 to be used within a distance equal to twice the member depth from the column or beam face for special moment frames or from sections where yielding of the reinforcement is likely to occur as a result of inelastic lateral displacements.

When using the Zap Screwlok System, there are no bar chemistry restrictions; bars may be ASTM A615 [or equivalent] or ASTM A 706.

All of the quality problems associated with welding are avoided.

There are no bar chemistries to establish; no weld qualification procedures to follow; no pre-heat or post-heat requirements, no radiographs to be performed and no risks of burns and accidental fires.

ZAP SCREWLOK BACKGROUND AND DESCRIPTION

The Zap Screwlok System was introduced into the U.S. construction market place in 1995 as a popular alternative to various rebar mechanical splice systems, welded joints, and traditional lap splices. Today, the Zap Screwlok System is in wide spread use, both domestically and internationally, as a preferred means of creating structural continuity in reinforcing steel systems.

The Zap Screwlok device comprises of a steel sleeve with sides converging internally to create a wedge shape. A series of screws, placed opposite the wedge, are provided to force the reinforcing bar into the wedge. At the time of installation, the rebar deformations become interlocked with the internal profile of the coupler body. Concurrent with rebar-coupler interlock, the points on the screws embed into the surface of the reinforcing bars, thereby providing a second mechanism by which the splice device attaches to the bar.

Two series have been developed: Zap Screwlok System SL

TEST DATA AND TEST PROTOCOLS

SL SERIES TEST DATA SL series test data is shown in ZAP SCREWLOK SL SYSTEM TEST DATA. 9 The results exceed the Type 1 specifications of ACI 318-05 and UBC 97 that

require a full mechanical splice to develop 125 percent of the specified yield of the bar.

TYPE 2 SERIES TEST DATA TYPE 2 series test results are shown in ZAP SCREWLOK SYSTEM TEST DATA. Special Provisions for Seismic Design are addressed in Chapter 21 of ACI 318-05. Section 21.2.6.1 states that Mechanical Splices shall be classified as either Type 1 or Type 2. A Type 2 splice is required to conform to the same strength provisions for Type 1 and develop the specified tensile strength of the spliced bar.

9 The results exceed the specified tensile strength of Grade 60 bar, namely 90,000 psi, thereby satisfying both the Type 1 and Type 2 specifications of ACI 318-05.

UBC The 1997 Uniform Building Code (UBC 97), in section 1912.14.3.4, requires a full mechanical splice to develop 125 percent of specified yield, fy, of the bar.

The use of reinforcement in members resisting earthquake-induced forces is addressed in section 1921.2.5. Restrictions are imposed upon the use of A 615 reinforcement per 1921.2.5.2. Under these restrictive conditions, section 1921.2.6.1.2 classifies mechanical connections according to strength. A Type 1 mechanical connection meets the strength requirements of 1912.14.3.4. A Type 2 mechanical connection develops in tension the lesser value of 95 percent of the actual ultimate strength or 160 percent of specified yield, fy, of the bar.

9 For bar sizes #4 through #11, the Zap Screwlok Type 2 series has been qualified to the Type 1 and Type 2 tensile requirements of the Uniform Building Code (UBC 97) as reported in ICCs Legacy Report ER-5461.

SLIP TESTS

Slip testing was incorporated into a comprehensive test program conducted for ICC Evaluation Services. Report UDR-TR-97-17, issued by the University of Dayton Research Institute, UDRI, describes the test program.

9 All results are less than 0.010 inches thereby meeting DOT slip-value criteria. CYCLIC STRESS REVERSAL TESTS

Sizes #10 and #11 were stress reversal fatigue tested at UDRI using ASTM A 615 bars and ASTM A 706 bars. Load-displacement curves were generated by UDRI at the start and end of each series of cycles. Final slip was determined from digital data.

10,000-stress reversal cycles from 25,000 psi in compression to +25,000 psi in tension was performed by CalTrans as part of their mechanical splice evaluation tests.

9 The results satisfied CalTrans requirements. 9 CalTrans approved Zap Screwlok Type 2 series.

HIGH CYCLE TENSILE FATIGUE TESTS

A series of high cycle tensile fatigue tests were performed at UDRI. Michigan DOTs specifications require that all splices tested shall develop a fatigue strength of 83 MPa (12 ksi) tension for more than 1,000,000 cycles.

To be considered for special high fatigue strength usage, all splices tested are required to develop a fatigue strength of 124 MPa (18 ksi) tension for more than 1,000,000 cycles.

Black and epoxy bars were tested in accordance with Michigan DOT requirements. Specimens were first fatigue tested for one million cycles at the standard 12-ksi range. The same specimens were then fatigue tested a second time at the high fatigue range of 18 ksi. Report UDR-TR-97-44 shows the actual number of cycles for each stress range and the cumulative number of cycles for each specimen. In the case of #8 Zap Screwlok, one specimen was subjected to a fatigue range of almost 24-ksi; this is a higher fatigue range than that required by Michigan DOT or than that defined by AASHTO.

9 In each case, it was reported that there was No damage, No slippage and No failure.

INTRODUCTION Barsplice Products, Inc. has conducted a series of tests on reinforcing bar mechanical splice sizes No. 4 through No. 14. The tests have been conducted on black and epoxy coated Zap Screwlok Mechanical Splices. The purpose of the testing is to ensure that products are manufactured to the quality standards of BPI's ISO 9001:2000 Quality System and are capable of exceeding strength requirements of various Building Codes. TENSILE TEST PROCEDURE Test specimens were loaded monotonically in tension to failure to determine the capability of the splice system. The tests were conducted in accordance with "Standard Test Methods and Definitions for Mechanical Testing of Steel Products", ASTM A370. The testing was performed to exceed the Type 2 strength requirements of ACI (American Concrete Institute) 318, Section 21.2.6.1, namely the specified tensile strength of Grade 60 reinforcing bar. This equates to 150% x specified yield strength of Grade 60 bar or 90,000 psi. All monotonic tension tests were carried out in a 600 kip Forney universal testing machine, located at the Barsplice Products, Inc. in-house laboratory. Current calibration certificates for the test machine are on file. All testing of mechanical splices at the Barsplice in-house lab is controlled within the BPI ISO 9001:2000 Quality System. COMPRESSION TEST PROCEDURE Test specimens were loaded monotonically in compression to exceed the strength requirements of ACI (American Concrete Institute) 318, Section 12.14.3.2, namely 125% x specified yield strength of Grade 60 reinforcing bar. All Compression tests were carried out in a 200 kip Satec universal testing machine, located at the independent testing laboratory of A-Lab Inc., Dayton, OH. TEST RESULTS Results of the tension testing are summarized in Table 1. Results of the compression testing are summarized in Table 2. The reinforcing steel used in these tests conforms to the requirements of ASTM A615, Grade 60.

SUMMARY (1) Tension test specimens exceeded the Type 1 strength requirements of ACI 318, Section

12.14.3.2, namely 125% x specified yield strength of Grade 60 rebar. (2) Tension test specimens exceeded the TYPE 2 strength requirements of ACI 318-05,

Section 21.2.6.1, namely the specified tensile strength of Grade 60 rebar. ASTM A615, Grade 60 has a specified tensile strength of 90,000 psi which is equivalent to 150% x specified yield.

(3) The TYPE 2 strength requirements stated in the 1997 Uniform Building Code (UBC) were

met*, namely the lesser value of 160% x specified yield strength of Grade 60 rebar or 95% x actual tensile strength of the rebar.

(4) Compression testing exceeded the minimum strength requirements of ACI 318, Section

12.14.3.2, namely 125% x specified yield strength of Grade 60 reinforcing bar.

* Bar size #14 has not yet been evaluated by ICC to the UBC strength requirements.
