一、前言砖墙是砖结构房屋的主要抗侧力构件,在地震力作用下,往往首先破坏而导致整幢房屋的损坏与倒塌。因此近年来国内外对墙体构件进行了大量的试验研究。由于砖砌体是由砖和砂浆两种材料组成,砌筑工艺以及几何尺寸等差异较大,使其力学参数也不尽相同,因此,根据我国砖 I. INTRODUCTION The brick wall is the main anti-lateral force component of a brick-structured house. Under the action of seismic forces, it is often the first to cause damage and collapse of the entire house. Therefore, in recent years, a large number of experimental studies on wall components have been conducted at home and abroad. Because brick masonry consists of brick and mortar, the masonry process and geometrical dimensions are quite different, and their mechanical parameters are not the same. Therefore, according to the
