圆弧倒角型隔板贯通节点试验研究
|
摘要
方钢管混凝土框架结构体系中,隔板贯通式连接已经被我国规程列为梁柱连接的推荐形式。但由于国内有关隔板贯通节点的研究资料较少,规程和规程中也未给出节点的计算理论与设计方法,在一定程度上制约了其在工程中的应用。
为配合方钢管混凝土结构的推广和相关设计规程的推出,本文在介绍了方钢管混凝土柱与H型钢梁的刚接节点形式和研究现状的基础上,对圆弧倒角型隔板贯通节点的力学性能进行了试验研究。
基于日本规程提出的隔板贯通节点静力拉伸承载力理论,对十一个节点模型试件的静力拉伸试验,研究了方钢管混凝土柱与钢梁翼缘连接的结构性能。介绍了各试件的破坏过程及特征,分析了节点域的应力传递机制,并对节点承载力实测值和理论计算值进行了比较分析。研究结果表明,圆弧倒角型隔板贯通式节点梁翼缘受拉模型具有较高的承载力和良好的延性,在钢管中填充混凝土有利于提高节点的屈服承载力和刚度,理论计算公式对于填充混凝土的试件偏于保守,但却高估了空钢管试件的承载力。
为研究隔板贯通节点的抗震性能,本文对四个十字型足尺试件进行了拟静力试验,介绍了各试件的破坏过程及特征,然后根据实测的滞回曲线,对节点的承载力、延性、耗能能力、刚度退化等抗震性能指标进行了详细的比较分析。研究结果表明,隔板贯通节点具有较好的延性和较强的耗能能力;钢梁翼缘与隔板的连接构造对节点的延性、耗能能力、刚度退化影响较大,圆弧倒角型节点比侧板加强型节点具有更好的抗震性能。
In frame structures with concrete-filled square steel tubular members, diaphragm-through joint has been regard as recommended type in technical specification of our country. However, because studies on diaphragm-through joints are very limited, calculating theory and design method are not well developed in the corresponding codes and regulations, which restrict its practice in the project.
To coordinate the promotion of concrete-filled square steel tubular column structure and the implementation of new design code, this paper summarizes joint types of moment resisting connections between concrete-filled square steel tubular column and steel beam, and simply introduces the present research of rigid joints. On the basis of above investigation, experimental study on cicrcular fillet diaphragm-through joints is carried out to understand its mechanical property.
Based on the tensile load-bearing capability theory of diaphragm-through joint presented in specification of Japan, eleven specimens of the joint model are studied by static tensile test to investigate the structure behavior of the connection between concrete-filled square steel tubular column and steel beam flange. The failure process and feature of each specimen are described and the stress transfer mechanism in the connection zone is analyzed. Then comparing analysis is executed on the measured value and the calculated value of bearing capacity of this joint. Research results suggest that cicrcular fillet diaphragm-through joint model has high capacity and good ductility and that the yield capacity and stiffness can be increased by the concrete filled in the tube. Load-bearing capability calculated from the theoretical formula is conservative for the specimens with the tube filled in concrete, but overly estimates the strength of the specimens without concrete.
In order to study the seismic performance of diaphragm-through joint, four full-scale cruciform specimens are studied under quasi-static test. The failure process and feature of each specimen are described. Based on the measured hysteresis loops, this paper makes a thorough comparing analysis on the index of seismic behavior such as load-carrying capacity of the joint, ductility, energy dissipation, and rigidity degeneration. The analysis results show specimens of diaphragm-through joint have good ductility and enough energy dissipation capacity. Details of the steel beam flange with the diaphragm have obvious effect on the ductility, energy dissipation and rigidity degeneration, and the seismic performance of joint of circular fillet type are better than those reinforced by taper plate welded to the beam flanges and diaphragm.
