Comments on Building Codes for Australia 1. General
a. Name of Country: Australia b. Name of Codes: AS1170.4 – Structural design Actions Part 4: Earthquake Actions in Australia
--- in English --- in Original Language
c. Issued by: Standards Australia d. Enforcement Year: Published in 2007 and enforced in 2008
2. Structural Design Method
a. Format: (please check) □ Working Stress Design : Allowable Stress ≧ Actual Stress □ Ultimate Strength Design: Ultimate Member Strength ≧ Required Member Strength
Limit State Design : Ultimate Lateral Strength ≧ Required Lateral Strength □ Other Design Method : (comment)
b. Material Strength (Concrete and Steel): Ultimate strength design is used in the material design Standards in Australia c. Strength Reduction Factors: Different strength reduction factors are used depending on the action and material type with values in the range 0.6-0.9. d. Load Factors for Gravity Loadings and Load Combination: 0.9xDead Load + Ultimate Earthquake Force 1.2xGravity Load + Ultimate Earthquake Force Gravity Load = Dead Load+ 0.3x Live Load e. Typical Live Load Values:
Office Buildings : 4 kN/m2
Residential Buildings: 1.5 kN/m2
f. Special Aspects of Structural Design Method
In case that your code is performance-based, please describe the fundamental seismic performance requirement. Design philosophy is to protect life and prevent collapse whilst allowing damage at the Ultimate Limit State Event.
