Investigation of Masonry Building Systems and Seismic Weakness Improvement Methods

Seismic performance is an important issue in the design of buildings located in seismic areas. One of the most important parameters in the design of structures is ductility (ductility; ductility plays the role of a fuse in the structure. Damage to a strong member (such as walls) that is expected to be able to maintain its stability in the structure in any case. The presence of a malleable member in the structure gives the occupants of the building the opportunity to leave the building during an earthquake. This is the same seismic expectation that comes from the structure, meaning that the structure does not act without warning and does not collapse once. In masonry buildings, the parameter of strength, especially shear strength, is very important. In this study, in order to know more engineers, to present the seismic weaknesses of masonry buildings during earthquakes and methods Fixing it during design and execution (before the structure is damaged and causes casualties and needs to be repaired) and also The wit of the damaged structure is addressed after the earthquake.
