在砖石混凝土混合结构中,当钢筋混凝土构件布置不当时,往往会引起砖石墙身的开裂。这些裂缝随着时间的增加而发展,宽度可达6～8毫米,甚至更大,时间长了就会影响建筑物的使用寿命。因此,研究这些裂缝的发生、发展和防止裂缝开展的措施是很有必要的。本文仅就沿墙身纵向设置的钢筋混凝土梁,引起墙身开裂的问题进行探讨。在建筑物中,这种裂缝常见的有两种形
In the mixed concrete structure of brick and stone, when the reinforced concrete components are arranged improperly, cracking of the masonry wall body is often caused. These cracks develop over time, and can be as wide as 6 to 8 millimeters in width, or even more. Longer periods can affect the useful life of the building. Therefore, it is necessary to study the occurrence and development of these cracks and to prevent cracks from developing. This article only discusses the problem of wall cracking caused by reinforced concrete beams installed longitudinally along the wall. In buildings, there are two types of cracks
