Civil 2013 V3.1 Release Nivil 2013 Enhancement1. Improvements in Pushover Analysis

1.1 Export Moment-Curvature Idealized Model from midas GSD to Civil

Moment-Curvature (M-Lumped) type hinge properties can be automatically generated based on the idealized moment-curvature curve obtained in midas GSD.

For P-M and P-M-M interaction type hinges, a number of Moment-Curvature curves with various axial forces can be imported at once.

GSD Imported Type skeleton curve is newly added to sim ulate the reduction of flexural capacity.

2.1 Improvements in Multi-linear Type Inelastic Hinge Properties

Perfect plastic primary curve of multilinear type hysteresis models can be defined in Inelastic Hinge Properties. In the old version, in order to simulate the perfect plastic behavior,

the user needed to enter the very small increment of force.

Compression-only and Tension-only primary curve can be defined.

Scale factor for displacement and force in m ulti-linear type hysteresis model is added .

Moving load analysis as per AS 5100.2 is new ly implemented.

Standard vehicles (W80, A160, M1600, S1600) and user defined vehicles (Truck/Lane, Train, Permit Truck) are supported. Accompanying lane factor can be automatically

considered.

Concurrent forces and reactions can be checked in Results by Max Value Item table.

Permit vehicle can be defined in BS moving load code for generating various number of wheels in one axle for special operations. Permit vehicle can be combined with other

vehicles in BD37/01 excepting for HA&HB (Auto) in Moving Load Case.

User defined HA, HB, and HA&HB vehicles are newly added for considering various type of vehicles and combination with perm it vehicle.

For user-defined HA&AB (Auto) vehicle, HA lane factor op tion is added and the exponential field 0.1 for 50 Moving Load Code > BS

Civil 2013 V3.1 Release Nivil 2013 Enhancement10. Improvements in Local Direction Force Sum

When bridge decks are m odeled using plate elem ents and main girders are m odeled using beam elements, resultant forces can be calculated in Local Direction Force Sum.

In the old version, the resultant forces were obtained only for the plate elements or solid elements only. In the new version, resultant forces can be obtained for the bridges

composed of Beam (deck) + Beam (girder) and Plate(deck) + Beam (girder).

Local direction force sum can be obtained in any construction stages. In the old version, Local Direction Force Sum was activated only in Post CS.
