［摘要］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。

Abstract:Because the orthogonal boundary beam is set around the pipe well, the clear height of the building is influenced. Based on the elements experiments, study was conducted on the behavior of the beam in whole process under static load. Some useful suggestions were given for design, and empirical measures for the capacity of this kind of beam were proposed.

Keywords:pipe well; fork-shape simply supported beam; finite element analysis; experimental study
