The Effect of Cast-In-Place Floor Slab on Strong Column-Weak Beam Mechanism of RC Frame Structures

Abstract:

For understanding the influence of cast-in-place floor slab on the failure mechanism of "Strong column-weak beam", nonlinear finite element simulation of a 1/2-scale one-story, two-bay RC frame specimen has been carried on using DIANA software. The analysis model was designed and constructed according to the design drawings of Xuankou middle school building. Through the comparison and analysis, it shows that the 3 D solid finite element model established is feasible to analyze the mechanical performance of RC frame, and the contribution of cast-in-place floor slab on the negative flexural capacity of frame beam, which is disadvantageous to realize the failure mechanism of "Strong column-weak beam", should not be neglected.
