Analysis ofnonlinear finite - element for ultimate tensile strength of gusset plate connections toslotted tubes with ansys program are carried out in this dissertation 本文采用通用有限元程序ansys对管板节点进行非线性有限元分析研究。
Tests consist of three parts : material property test of panel , slippage coefficient test of bolt connection and cyclic load test of end - plate connections 试验共分3部分：钢板单向拉伸试验；连接抗滑移系数试验和端板连接循环加载试验。
Under tensionloading , these gusset plate connections can be susceptible to shear lag failure of thehss since only a part of the tube cross - section is connected to the plate 由于钢管截面只是部分和钢板连接,在拉力作用下,管板节点易发生剪切滞后破坏。
In order to study the hysteretic behavior of end - plate connections and verify the reliability of theoretical method , 8 end - plate species were tested under cyclic load 为了分析端板连接的滞回性能并验证理论分析的可靠性，本文进行了8个端板连接试件的循环加载试验。
Finite - element study on the ultimate strength of gusset plate connections to slotted tubes and full scale tests on the ultimate strength of the connections are researched in this dissertation 本文研究的主要内容为管板节点受压极限承载力非线性分析和足尺试验研究两部分。
Three kinds of bolted extended end - plate connections are tested . a series of parameters representing connections behavior are investigated and compared between the three types of connections . 2 进行了三种螺栓端板连接节点的足尺试验，分析比较了它们的承载力、塑性变形能力等； 2
A full - scale experimental study and associated nonlinear finite element analysiswere undertaken to study the ultimate tensile strength of gusset plate connections toslotted tubes in this dissertation 本文研究的主要内容包括管板节点受拉极限承载力非线性有限元分析和足尺试验研究两部分。
Two hypothesises , different from the traditional viewpoints , about stress distribution in beam section at the connection of beam and end - plate are presented by author to determine the ultimate moment of end - plate connection 其计算过程分为两步： ( 1 )计算梁受拉翼缘的极限拉力； ( 2 )计算端板连接的极限弯矩。
Because of the geometry complexity of bolted beam - column end - plate connections , the strength models presented in the past few decades can not predict the ultimate strength of end - plate connection in a satisfactory precision 钢框架梁柱端板连接是应用最为普遍的连接形式之一，但是由于其几何形态的复杂性，节点强度的计算方法并不十分令人满意。
Bolted end - plate connections are often being used in light - steel frame owing to their simplicity and economy of fabrication and erection , and the study about its behavior and design method is more and more being taken seriously 端板连接节点因其制作安装简便和经济而成为轻型钢结构中普遍采用的连接形式，其性能和设计方法的研究日益受到重视。
