1) beam-column effect 梁-柱效应 2) beam-column effect 梁柱效应 1. For such structures,beam-column effectanal. 本研究通过对几个工程实例的计算,表明在有些结构尤其是高层建筑结构中,几何刚度对计算结果的影响比较显著,进行梁柱效应分析是必要的。
The study documented in this report provides a simple means of combining a two-dimensional foundation with a beam-column structure for use in preliminary design and analysis. The report demonstrates that a foundation can be investigated and formed independently of the structural beam-column matrix. ...
moment, or transverse load. Beam columns are found in frame-type structures where the columns are subjected to other than pure concentric axial loads and axial deformations, and where the beams are subjected to axial loads in addition to transverse loads and flexural deformations.SeeBeam,Column ...
I believe that the matrix is also laid out in the COSMIC NASTRAN Theoretical Manual, although I don't have my copy at hand.If you still need more info, let me know.Bob kiso (Structural) (OP) 28 Dec 01 00:48 Yes, I mean the beam column element. I just didn't know that was...
