建立了钢框架在高温下喷水快速冷却的有限元模型，分析了钢框架在高温下的动态力学和变形。模拟结果表明，在此过程中产生了显著的力学耦合效应，且快速冷却时的截面应力明显大于升温时的截面应力。同时，快速冷却时，梁的应力和变形主要与冷却速度和位置有关，远大于柱的应力和变形。在消防中，一楼或二楼的结构比其他楼层的结构在快速降温时更危险。研究结果可为钢结构设计和消防设计提供理论参考。
A finite element is established for analyzing the dynamical mechanics and deformation of steel frame at high temperature when it is rapidly cooled down by spray water in fire fighting. The simulation result shows that remarkable mechanical coupling effects are produced in the process, and the sectional stress in rapid cooling down is found considerably larger than that in heating-up. Meanwhile, the stress and deformation of a beam mainly related to cooling rate and location are much larger than those of a column in rapid cooling. In fire fighting, the structure on the first or second floor was more dangerous than those on other floors in rapid cooling. These results could provide a theoretical reference for the design of steel structure and fire fighting.
