The distribution of pre-stress in the multi-layer structure is related to the global and localrigidity, the contact area and the clearance of superimposition.
The paper studies the relation between the section rigidity and the service time of the RC bridge under the composite effect of the expansion of cracks and the whole or local corrosion.
分别研究了钢筋混凝土桥梁在整体腐蚀和局部腐蚀同裂缝扩展的组合效应下截面刚度与服役时间关系。
