摘要:
研究了空间相关地震激励作用下两层空间刚架的动力响应,计算了结构拟静力、动力及总反应方差,多点输入考虑了以下几种情况:①具有相位差及相干损失的多点输入; ②仅有相位差的多点输入; ③仅有相干损失的多点输入; ④一致输入.比较了各种输入情况下的结构反应方差,分析了偏心对反应方差的影响.
Abstract:
The stationary random responses of tow-layer spatial frame subjected to spatially coherent excitations are investigated and the pseudo-static, the dynamic, and the total response variations are calculated. The results, together with those obtained by neglecting ground motion phase shifts and those by neglecting ground motion coherency losses are compared with the corresponding structural responses variation to a single input. The influence of the eccentricity is analyzed and some useful conclusions are given.
