钢桁架连梁抗震性能试验研究
|
摘要
高层建筑结构中,连梁起着调节和保证联肢墙和核心筒筒壁侧向刚度的作用,是剪力墙结构抗震设计的第一道防线,合理设计的连梁可以起到很好的耗能作用。各种震害和试验研究表明,建筑结构的倒塌,主要是由于结构构件的耗能和塑性变形能力小于所需要的能力。对于普通钢筋混凝土连梁,降低连梁的刚度可增大剪力墙的延性,但连梁刚度过小则会因承载力不足而过早破坏,影响了剪力墙整体性能的发挥,特别是跨高比小的连梁,在达到刚度要求时,不能满足延性连梁的要求。相比于钢筋混凝土连梁,钢结构连梁具有承载力高、自重轻、节约材料、截面尺寸小、抗震性能好等突出优点,将成为连梁结构体系的重要发展方向。
本文作者所在研究组提出了钢桁架连梁,它采用钢桁架形式代替传统的钢筋混凝土连梁结构。研究这种结构形式连梁的承载力和抗震性能,分析其抗震性能的影响因素,对钢连梁的研究设计和实际工程的应用有着重要的价值。为此,本文对所提出的钢桁架连梁展开了试验研究,设计了两种不同结构形式的钢连梁——交叉腹杆桁架连梁和无交叉腹杆连梁。通过对4个试件的伪静力试验,了解钢桁架连梁在反复荷载作用下的破坏机制,探讨型钢埋入长度的可行性,对比分析两种结构的延性、强度和刚度退化情况,并对其耗能能力进行评价。
论文最后,针对试验结果,对这两种结构形式连梁的抗震性能作了归纳和总结,并提出该课题在参数分析、节点构造及理论分析等方面有待深入研究的若干问题。
In the high-rise building structure, the coupling beams which are the first line of defense in seismic design can influence and assure the lateral stiffness of the whole structure, reasonable design of coupling beams can play a good role of energy consumption. Kinds of earthquake disasters and studies showed that the reasons of building collapsed were the capacity of energy consumption and plastic deformation of components which designed less than the required capacity. For ordinary reinforced concrete beam, to reduce the stiffness of coupling beams can increase the ductility of shear walls, but too small stiffness can lead the premature damage for inadequate bearing capacity that affected the overall performance of the shear wall, especially for the small-span-to-depth ratio coupling beams which stiffness enough meet not the requirements of ductility. Compared to concrete beam, the steel structure beam with the prominent advantages of high-capacity, light weight, material savings, small size of cross-section, good seismic performance will become the direction of coupling beam structure development.
Steel truss beam using steel truss to replace the traditional form of reinforced concrete beam, have been given by our research group. To study the bearing capacity and seismic performance as well as the impact of seismic of this structure forms would provide important values to the actual design and engineering applications. Therefore, the author designed two different structural forms of steel beam - cross abdominal trusses beams and without cross-abdominal trusses beam for experiment research. To learn the failure mechanism, explore the feasibility length of steel buried in concrete, analysis the degradation of strength and stiffness, as well as evaluate energy consumption of the two structural forms through four specimens of pseudo-static test.
In the end, the author summarized and summed up the seismic performance of the two structural forms based on the test results and analysis, and pointed out the further studies on parameters, node structure and theoretical analysis.
