［摘要］設(shè)備管井周邊設(shè)置正交邊梁會影響建筑凈高，運用叉形簡支梁合理解決了此類問題。通過對叉形簡支梁的足尺試驗，分析了在靜力加載全過程中應(yīng)變與轉(zhuǎn)角的變化特點，認(rèn)識了此類構(gòu)件的受力性能。結(jié)合試驗現(xiàn)象，用有限元程序進(jìn)行了數(shù)值模擬，對梁的結(jié)構(gòu)設(shè)計提出一些建議和構(gòu)造要求，同時也為設(shè)計提供了依據(jù)。

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
