EXPERIMENTAL AND FEM RESEARCH ON THE STRUCTURAL REASONS AND FACTORS RELATED TO CRACKS IN CAST-IN-PLACE FLOOR SLABS OF MASONRY RESIDENTIAL BUILDINGS

摘要

The cast-in-place floor slab is the primary structural form of floor widely used in residential buildings at present. While cracks problems often occur in the slabs without variable loads applying on them. Based on the model experimental study, nonlinear finite element analysis is used to research the structural reason of slab cracking and the effects of several structural factors to the slab cracking problem. Finally, some significant conclusions are drawn.
