Equivalent Static Wind Load on Light weight Steel Structure with Gabled Frames

Abstract:

The estimation of wind load on light weight steel structure with gabled frames in the current code doesn’t involve the spatial correlation of fluctuating wind load. The distribution and magnitude of wind load on light weight steel structure with gabled frames are obtained with load response correlation (LRC) method according to international wind load codes and standards. Compared with the calculation results based on the current code, the estimation of equivalent static wind load on light weight steel structure with gabled frames is proposed. Based on wind load time series obtained from the synchronous multi pressure measurement on a rigid gable roof building model, a finite element model for light weight steel structure with gabled frames is established. Calculation results show the wind load effects obtained by the proposed estimation method are much closer to the extreme values of dynamic time history analysis, and the expression is concise and practicable.
