查询词典 slab bridge

The assessment formula for shear capacity was established as well, and in which various impact factors of shear strength was considered comprehensively.3. Directed against the main forms of transverse connection in concrete beam bridges, model test and finite element analysis were carried out to find the impact laws of damage on concrete T-beam bridges, in which the three ways of hinged joint, flange rigid connection and cross slab rigid connection were considered. Transverse distribution and degenerate state of transverse connection were studied under various damage conditions. Based on the analysis of test and simulation results, the rule of live load adjustment coefficient of T-beam bridge was put forward, as well as the calculation formula.4. In view of the influence of the damaged transverse connections to load effect, the load effect model was amended by live load adjustment coefficient.

依据损伤出现频率与重要性等级，提出典型损伤混凝土梁式桥按体系损伤、构件损伤和材料损伤三个层次进行评定的原则。2、基于构件和材料层次损伤评估研究成果，对比分析损伤机理和适用条件，提出了《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)抗弯承载力修正计算公式、抗剪承载力修正计算公式以及综合考虑抗剪强度影响因素的抗剪承载力评定公式。3、针对混凝土梁式桥主要横向连接形式，分别按铰结、翼缘刚接和横隔梁刚性连接损伤对T桥梁桥承载能力的影响进行了模型试验和有限元分析，研究了不同损伤工况对T梁桥荷载横向分配的影响及横向连接状态退化情况。
