新型叠合粱一柱端节点试验研究

STUDY ON THE NEW COMPOSITE BEAM-COLUM FRAME EXTERIOR JOINTS

新型叠合梁-柱端节点的梁中采用了端头锚、剪力键等不同于传统的锚固、连接构造措施。这些构造措施有效地将单个结构构件联成相互统一的整体,保证了结构的整体性能。在现浇等强设计的基础上,通过伪静力试验分析了梁-柱端节点的抗震性能以及节点连接构造措施、薄弱部位的处理等方面对其各性能特性的影响。

In the new composite beam - column frame exterior joints, end anchors, shear connectors etc were adopted, which are different from normal anchorage connection of constructional measures. Constructional measures make the structural members effectively connected to a unity, ensure the whole performance of the structure. In this paper, on the basis of equivalent strength design with the integral cast - in - place concrete structure, through the pseudo - static test, the constructional measures in anti - seismic of each joints in the new assembled monolithic concrete construction was presented ; basis on contrast experiments between two beam - column frame exterior joints, some aspects on the performance of the new assembled monolithic concrete construction were analysised, such as the effect of the monolithic connection cnstructional measures of the nodes,the treatment of weak parts.
