What are the main structural measures of masonry structure wall?

Hello, the structural measures of masonry structure wall mainly include three aspects, namely expansion joint, settlement joint and ring beam.

Due to the change of temperature, the wall is prone to cracks. The house can be divided into several units by expansion joints, so that the length of each unit is limited to a certain range. Expansion joints should be located where temperature changes and shrinkage deformation may cause stress concentration and cracks in masonry. Load-bearing walls should be set on both sides of expansion joints, and their foundations cannot be separated.

The uneven local foundation soil will cause excessive uneven settlement and cracking of buildings, which will seriously affect the normal use of buildings and even endanger their safety. In order to prevent the emergence of settlement joints, the building can be divided into several units with good stiffness by settlement joints at appropriate positions, and the foundation of settlement joints must be separated.

Reinforced concrete ring beam can resist the tensile stress in the wall caused by uneven settlement of foundation, and at the same time, it can increase the integrity of the building structure and prevent the adverse effects caused by vibration (including earthquake). Therefore, ring beams should be continuously arranged on the same horizontal plane and form a closed shape.
