Researchers from University of Leeds Publish New Studies and Findings in the Area of Construction Engineering

摘要

2011 MAY 4 - (VerticalNews.com) -- According to recent research from Leeds,rnUnited Kingdom, "Steel portal frames were traditionally designed assuming that beam-tocolumnrnjoints are ideally pinned or fully rigid. This simplifies the analysis and structural designrnprocesses, but at the expense of not obtaining a detailed understanding of the behaviour of thernjoints, which in reality, have finite stiffness and are therefore semi-rigid."
