本文是根据《抗震区空心砖承重结构住宅建筑的研究》课题所进行的大量试验研究与弹塑性分析计算的结果,集中讨论了无筋和各种配筋墙片抗剪强度的计算。给出的计算公式考虑了剪跨比与翼缘的影响,并纠正了当正应力σ_o较小时用抗震规范TJ 11-78中主应力公式来计算偏于不安全的缺点,计算公式与试验结果比较接近。可供研究和设计参考。
This article is based on a large number of experimental studies and elasto-plastic analysis of the “Research on Residential Buildings with Hollow Brick Load-bearing Structures in Earthquake-resistant Zones,” and focuses on the calculation of the shear strength of unreinforced and various reinforced wall segments. The formulae given take into account the influence of the shear span ratio and the flange, and correct the disadvantages of using the principal stress formula of earthquake resistance specification TJ 11-78 to calculate the unsafe ones when the normal stress σ_o is small, and the formulas and test results are calculated. It is closer. For research and design reference.
