Welded Continuous Frames and Their Components. Rotation Capacity of Beams

摘要

An analysis of a three span beam is used to illustrate the effect of yield strength on rotation capacity. The analysis consists of: determination of the rotation capacity required to permit the formation of a mechanism, determination of the rotation capacity available, and determination of limiting values of length to depth and unbraced length to ensure that adequate rotation capacity is available. The limiting values of length to depth ratio resulting from the rotation capacity analysis are compared with those required to meet a working load deflection criterion. (Author)
