外加钢筋混凝土构造柱提高砖墙抗震性能的试验和分析

Test and Analysis of the Earthguake-Resistant Behaviour of the Brick-Walls with Reinforced Concrete Columns

本文对外加扁形及方形钢筋混凝土构造柱墙体进行了循环加载的足尺寸墙体试 验，并用（１）的方法对墙体进行了平面应力问题的有限元弹塑性和裂缝开展分析。 认为只要外加柱和墙体的联结能保证两者直到破坏不脱开，则外加柱的作用和埋入在 墙内的构造柱基本相当。研究还表明，配置单排钢筋的扁形柱与双排钢筋的方形柱， 在柱断面和配筋量相同的情况下，对增强墙体抗震能力两者有同等的效用。

The tests of full scale walls with reinforced concrete columns with rec- tangular and square sections under periodic load are discussed in this paper. Using the finite element described in ref. [ 1], the elasto-plasticity and crack growth processes of the brick-walls are analysed. We conclude that the con- nection of the walls and the columns does not separate until the walls colla- pse, and the effects of the reinforced concrete columns added are basically equivalent to those buried in the walls. The study also notes that the rectangular columns with the single row of the steel bars are equal to the square columns with the double rows of the steel bars for the strengthening of the earthquake-resistance capability provided the sectional areas of each column and the steel bars involved keep unchanged.
