摘要:
以广州观音沙大桥为工程实例，根据现场测试结果，提出一种实用算法，用于模拟混凝土箱形梁桥的日照温度效应．建立箱梁横断面的温度分布模型，将温度载荷转换为等效结点载荷；建立空间梁单元模型，计算桥梁结构的挠度和应变，并考虑环境气温对预应力钢索应力的影响.该算法可应用在施工监控中实时调整桥梁结构的挠度和预防温度裂缝．
Abstract:
A method to compute the solar thermal effects over cross sections of the concrete box-girder bridge, based on the measurements at the Guanyinsha Bridge, was proposed. The temperature loads of concrete box-girder bridge by means of the temperature distribution model were transformed to equivalent nodal forces. The deflection and strains of the bridge structure were calculated by using the three-dimensional beam element model. The influence of air temperature on the stresses of the pre-stressed tendons was considered during the computation process. This method can be applied to correcting the deflection of the bridge structure during construction, and to prevent from the thermal cracking.
