钢筋混凝土框架结构的施工和使用中 ,常常因结构间的处理不当及构造上的原因 ,导致填充墙开裂。一、填充墙裂缝的形式１．钢筋混凝土框架梁下填充墙垂直裂缝一般出现在框架梁弯矩最大、变形最大部位 ,裂缝沿填充墙灰缝自上而下发展（图１） ,呈踏步状。钢筋混凝土框架梁下墙体
Reinforced concrete frame construction and use of the structure, often due to improper handling of the structure and structural reasons, leading to infilled walls cracking. First, the form of wall cracks filled 1. The vertical cracks in the infill walls under the beam of RC frame usually appear in the frame with the largest bending moment and the most deformed part. The crack develops along the wall of the infilled wall from top to bottom (Figure 1). Reinforced concrete frame beam under the wall
