一种改进的连梁形式的受力性能分析

Mechanical Performance Analysis of an Improved Form of Coupling Beam

剪力墙设计中连梁设计是一个难点,双连梁虽然能解决超筋的问题,但存在弹性刚度下降的弊端.针对这一问题,首先通过试验得出双连梁和单连梁各自的优点和缺点;然后依据试验试件,建立有限元模型模拟试验模型,得出有限元模型模拟的可行性;最后提出4种不同的连梁形式,通过有限元模拟,得出一种受力性能上既拥有双连梁的优点又能克服双连梁的不足,且施工便利的连梁形式.

The coupling beam design in the shear wall structure is a difficult point. Double coupling beam may solve the problem of super steel, but the disadvantage is that its elastic stiffness is decreased. In order to solve this problem, first of all, the respective advantages and disadvantages of the double coupling beam and single coupling beam were concluded through experiment. And then on the basis of testspecimens, the finite element model was set up and the feasibility of the finite element model simulation was concluded. Finally four different forms of coupling beam were put forward, and through the finite element simulation, a kind of coupling beam was obtained which both has the advantages of double beams in mechanical performance and can overcome the shortage of the double beam, and is convenient to construct.
