空腹桁架式结构转换层的试验研究

Experimental Research on Transfer Story Structures of Tall Building

本文结合实际工程，对高层建筑梁式和空腹桁架式转换层结构进行了试验研究，对比分析了两种形式转换层在竖向荷载和水平往复荷载作用下的破坏形态、承载力、位移、耗能能力、滞回特性等，研究成果表明空腹桁架式转换层有许多优点，为工程应用提供了理论依据。

Based on an actual project, two types of transfer story structures are introduced in this paper,one being the deep beam structure and the other the vierendeel truss in shear wall supported byframes. Vertical loading and cyclic horizontal loading tests were carried out for these two types oftransfer story structures. The failure pattern, load capacity, deformation characteristics, energydissipation capability, hysteresis curve behavior have been discussed based on the test results,which show that the vierendeel truss is superior to the transfer beam in many cases.
