Research on cracks of reinforced concrete continuous beam bridges FAN Liang，ZHOU Zhi-xiang，REN Chao 2004, 23(5): 8-11.  Abstract ( )   PDF (1184KB) ( )   Cap-beams on the middle pier of continuous beam bridges in municipal cross roads are often omitted for the reason of beauty. But a plane analysis is often used in general designs. An actual two-span continuous beam bridge is calculated based on both plane analysis and spatial analysis and the results are contrasted in this paper. The reasons of cracks of the beams are discussed. A dangerous design result may be obtained for the continuous beam bridges which has no cap-beams on the middle pier if References | Related Articles | Metrics
