Research Precast Fool Slab of Massonry Building Roof Reinforcement Methods

Abstract:

Most of the existing building floor roof of brick structure is precast floor slab structures, which structural integrity is not good. In the earthquake, the floor is easy to fall off from the wall, causing casualties and economic losses. Vertical bearing capacity of precast floor slab are usually able to meet the requirements. In most cases the floors have been fall off from the wall before the floors were damaged, Stability of the outer plane of the floor itself to be adequate.By analyzing the patterns and characteristics of precast floor slabs crack under seismic force often appear, this paper presents that the prefabricated floor flat overall reinforcement scheme, which the application of steel band with end portion of the floor a holistic reinforcement,and finite element software ABAQUS be counted cases,the integrity of the reinforced floor to achieve significant improvement, and maximum allowable displacement can be controlled within a limited value.
