| 摘 要： | 热胀冷缩是建筑物的普遍特性。温度变化时使超静定结构中的构件产生内力，温度变化越大，结构中的力作用也越大，以至不能，忽视，本文剖析了杆件的温度变形后，将温度对结构的作用划为等价内力。高度较大的结构，一般其杆件截面尺寸亦较大，因而，杆件的剪切变形应该考虑。文中计算了在季节温差、内外温差和日照温差等三种温差下框架结构的内力。

| Abstract: | It is an important characteristic that buildings expand when heated and contract when cooled.When the temperature changes,it is possible for the internal forces instructural members of ultable structures to occur. The greater the temperature changes,thegreater the force actions in structures.In this paper,the thermal effects are converted into the equivalent internal forces,and a group of formulas on equivalent internal forces and element stiffness matrices considering the shearing deformation are derived.Three examples onthe effects caused by seasonal temperature difference,inside--and--outside temperature difference and sun--exposure temperature difference upon frame structures are given. |
