施工温度对巨型贮煤筒仓结构性能的影响

Influence of construction temperature on performance of giant reinforced concrete coal silo

温度作用对巨型贮煤筒仓结构性能有不可忽视的影响,但是筒仓混凝土施工合拢温度对结构在使用过程中的性能影响,尚未有详细论著.本文运用ANSYS有限元分析软件对一个直径120 m的钢筋混凝土圆形贮煤筒仓进行分析,得出施工温度与筒仓结构响应之间的关系,用以指导在不同季节施工的此类筒仓设计.

Temperature action has a considerable effect on the performance of giant reinfoced concrete coal silos.But it had not been discussed in detail that what influence would be exerted by the constuction temperature.Some researches are carried out for a circular coal silo with diameter of 120 m by the finite element analysis software ANSYS.The relationship between construction temperature and silo performance is found,so as to give reference to the design work of similar silos to be built in different seasons.
