【摘要】 本文对粘钢混凝土梁在受载情况下的应力分布规律进行了理论分析和三维非线性有限元计算,考虑了外粘钢板的粘接部位不同和逐级加载情况下对混凝土内裂纹开裂及扩展区规律的影响,为实际粘钢加固工程提供了定量分析和理论依据。更多还原

【Abstract】 In this paper, the stress distribution law of loaded concrete beam sticked with streel plate is analyzed. The theoretical analysis and 3-D nonlinear finite element method is adopted for calculation, and the changing law of the slight crackle development zone is disscussed. The theoretical basis and quantitative analysis for steel-adhered reinforcement engineering are finally proposed.更多还原
