The results show that the seismic response of the inequable loess stratum has the obvious magnification effect. 算例结果表明，非均匀黄土地层的地震反应具有明显的放大作用。
Effects of multi-support excitations on seismic responses of large-span trussed gable frames were investigated by time-history method. 摘要以大跨度门式桁架结构为研究对象，用时程分析法考察了多点输入对不同跨度结构地震反应的影响。
