一、概述砖结构由于具有较好的使用功能和低廉的造价,因而使用广泛。但砖砌体的抗拉、抗剪强度和延性较差,砖结构房屋的抗震能力较低,在国内外的历次地震中,遭到了较为严重的破坏。改善和提高砖结构房屋抗震性能的途径有二:一为提高砖砌体的抗剪强度和剪切延性;二为提高砖砌体的抗弯强度和弯曲延性。前一种多用于多层房屋,后一种多用于空旷房屋和厂房等。本文介绍提高砖砌体抗弯能力的一种有效的措施:在砖砌体之中或外部配置纵 I. Overview Brick structures are widely used due to their good use and low cost. However, the tensile strength, shear strength and ductility of brick masonry are poor, and the earthquake-resistance of brick-structured houses is low. In the earthquakes at home and abroad, they were seriously damaged. There are two ways to improve and improve the seismic performance of brick-structured houses: one is to improve the shear strength and shear ductility of brick masonry; the other is to increase the bending strength and bending ductility of brick masonry. The former is mostly used for multi-storey houses, and the latter is mostly used for empty houses and factories. This article describes an effective measure to improve the bending capacity of brick masonry: vertical or horizontal placement in brick masonry
