Dynamic Analysis on the Light-Weight Portal Frame with Different Slopes

Abstract:

Build up a group of light-weight portal frame models with different slopes by SAP2000 software. Conduct dynamic time-history analysis on light-weight portal frame models with different slopes under the EI Centro wave. The results show that: The maximum positive and negative displacement and acceleration of the light-weight portal frame presents a variation rule as the the slope increasing; the influence of the slope on the maximum positive and negative displacement of the frame is relatively small, while it is big on the maximum positive and negative acceleration; the acceleration amplification coefficient of the frame decreases as the slope increasing when the slope exceeds a limit, which show that the earthquake damage of the large slope light-weight portal frame increases as the slope increasing.
