摘要
对一座变截面刚架人行天桥在超负荷运营情况下进行了变形、内力分布以及结构的固有自振频率和振型计算 ,并根据计算结果对天桥结构作了整体稳定性和局部稳定性分析 .计算结果与实测结果吻合 ,可作为该桥质量检测与评价的理论依据 .文章对该类天桥的设计也有实际参考价值 .
The pedestrian bridge with taper section in exceeding load state undergoes deflection, distribution of internal force, inherence frequency and model calculation, and an analysis is made on the global and local stability of the bridge. The calculation results are consistent with the test. That can be regarded as the academic foundation for quality examination and the evaluation of the pedestrian bridge with taper section and have practical referential value for this kind of bridge.
