摘要:
为研究不同梁柱连接节点构造以及了解内填再生混凝土、梁柱截面尺寸对轻型钢管再生框架抗震性能的影响,本文提出了4种新型装配式节点构造,进行了6个框架试件的低周反复荷载试验,分析了各试件的破坏形态、承载能力、滞回性能、延性、强度及刚度退化、耗能能力等。结果表明:节点构造对框架抗震性能影响较大,本文提出的加强型节点构造可显著提高钢管再生混凝土框架的承载力、刚度及耗能能力;内填再生混凝土可以显著提高轻钢框架的抗震性能,耗能能力提高635.7%;适当增大梁柱截面尺寸有利于提高结构的承载力、刚度及延性。
Abstract:
In order to investigate the different construction of column to beam joints and to understand the effect of recycled aggregate concrete (RAC) and cross-section of beams and columns on the seismic performance of recycled aggregate concrete filled light steel tubular frame structure, four new types of assembly joints are proposed. A low cyclic loading test of six frame specimens has been carried out. The failure characteristic, load bearing capacity, hysteretic property, ductility, strength and stiffness degradation, energy dissipation were analyzed. The results show that the different construction of joints has a great influence on the seismic performance of the frame. The reinforced joint proposed in this paper can significantly improve the bearing capacity, stiffness and energy dissipation capacity of the recycled aggregateconcrete-filled steel tube frame. The seismic performance of steel frame can be improved and the energy dissipation capacity can be increased by 635.7% with RAC filled in the steel tubes. Appropriately increasing the size of section on beams and columns can improve the bearing capacity, stiffness and ductilityof the structure.
