考虑井字梁空间效应的框架结构抗震性能分析

Research on the space effects and the earthquake-resistant behavior of grillage beams

框架结构与井字梁楼盖体系相结合,在实际工程中得到广泛应用。通过对这种结构的抗震性能实验研究,分析了该种结构的滞回特征、破坏特征、延性和井字梁在水平地震作用下的空间作用。

The grillage-beamed floor that can resist vertical loads very well is a kind of useful structures in many buildings with big space and large span.However,in many,this floor has been used with the seismic frame and has became a new structure.The theoretical analysis and experimental study of space effects and earthquake-resist- ant behaviors of this new structure are performed.Theoretical results agree well with the experimental ones,and some seismic measures are put forward.
