设备管井周边设置正交边梁会影响建筑净高,运用叉形简支梁合理解决了此类问题。通过对叉形简支梁的足尺试验,分析了在静力加载全过程中应变与转角的变化特点,认识了此类构件的受力性能。结合试验现象,用有限元程序进行了数值模拟,对梁的结构设计提出一些建议和构造要求,同时也为设计提供了依据。 Equipment set around the tube wells will affect the construction of orthogonal beam side of the net, the use of simple supported beam to solve such problems. Through the full scale test of the fork-shaped simply supported beam, the change characteristics of strain and rotation angle in the whole process of static loading are analyzed, and the mechanical properties of such members are recognized. In combination with the experimental phenomena, numerical simulation is carried out by using the finite element program, and some suggestions and structural requirements for the structural design of the beam are also provided, which also provide the basis for the design.
