Numerical research bolts' effect on marshalling wall stiffness with vertical cracks

本文提出了砌体结构墙体刚度的概念 ,并给出其表达式。运用SCAD有限元程序对含纵向裂隙砌体结构刚度进行分析 ,研究了裂隙的数目、长度及分布对墙体刚度的影响 ,以及锚杆对墙体的刚度及张开度的控制作用 ,分析结果表明 。

In this paper the concept of wall stiffness with marshalling structure was proposed, and its computing formula was given. The effect of crack numbers, length and distribution on wall stiffness with vertical cracks was analyzed, and the control of bolt on wall stiffness and crack opening was studied. The results show that the bolt have important value to improve wall stiffness with vertical cracks.
