| 摘 要： | 温度变化是混凝土梁的作用之一．在温度作用下，若混凝土中的温度变化是非均匀的，则虽然静定混凝土梁横戴面上的内力为零，但仍然会在结构中产生温度应力．本文采用弹性力学方法，视静定梁为平面应力问题，将应力函数取为三角级数，计算了静定梁在一般温度分布时的应力．然后取日照温度变化．T(x，y)＝Toe^-kty，确定了好定混凝土梁温度应力的级数解．

| Abstract: | Temperature changes are one of the main actions in concrete beams If temperature changes in concrete beams are no even, the internal forces in static beams will be zero and temperature stresses will still be produced With elastic mechanics method, regarding static beams as plane stress problems and putting stress functions to trigone progressions, this paper computes the stresses in static beams under action of general temperature changes, and then determines progression solutions of temperature stresses in static concrete beams with putting temperature changes to T(x,y)=T 0e -ky |
