砖结构抗震修复加固计算

本文在分析有关单位现有试验资料的基础上,提出了用水泥砂浆抹面、钢筋网水泥砂浆抹面及外加钢筋混凝土柱修复加固砖墙,用钢筋网水泥砂浆抹面及外包角钢加固砖柱,用外包竖向和环向扁钢加固砖烟囱的计算方法。与现有的计算方法相比,本文所述方法的计算结果与试验值更为接近。

Calculating Methods of Strengthening and Repair of Brick Masonry Structures for Earthquake Resistance

Calculating methods of strengthening and repairing measures of brick masonry structures are described in this paper. These methods are based on the available testing data of the institutes concerned. The strengthening and repairing measures used are as follows.1. Cement mortar coating, reinforced cement mortar coating attached to the wall surfaces or reinforced concrete columns with tie beams were used for strengthening walls.2. Reinforced cement mortar attached to the surface or steel angles at the corners were used for strengtheing columns.3. Vertical and circular steel strips attached to the surface were used for strengthening chimneys.This paper shows that the calculating results with this methods are more close to the testing data than those calculated by the availabe current methods.
