基于裂缝特征的钢筋混凝土板式结构评估研究

Research on evaluation of reinforced concrete board structure based on crack feature

基于 4片钢筋混凝土板梁室内试验的裂缝特征 ,经回归分析及结构非线性分析 ,建立了以裂缝统计特征推测结构的受压区高度、变形曲率 ,进而预测结构配筋率的方法 ,从而达到对结构性能进行有效评估的目的。该方法简便可行 。

Based on crack distinctive feature obtained from 4 reinforced concrete slab girders test,through regressive analysis and nonlinear analysis,the method that can forecast structural press region height,deformed curvature and structural steel ratio is established. Structural performance can be effectively evaluated by it. The method is simple, convenient and low in cost.
