Prestressed concrete box girder bridges are widely used in long span bridges , and will be more widely used . but their calculation theory isn ? very perfect in the present 预应力混凝土箱梁桥在大跨径桥梁中得到广泛使用,且有着广阔的应用前景,但其计算理论还不尽完善。
It has been proved by examples of engineering practice that temperature fields did great effect on the stress and line deformation of long - span pc continuous box girder bridges 工程实例表明,温度场对箱梁的温度应力和挠度有很大的影响。使用不同的温度梯度模式计算得到的梁内温度应力相差非常大。
Purpose of this paper is to test whether a prestress continuous box girder bridge qualifys for the safe property in wuhan city , then provides scientific data for the subsequent run 武汉市某立交桥工程修建完工,受当地城建委的委托,武汉理工大学土木工程与建筑学院将对该工程实施动、静荷载试验。
A box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
