Concrete plasticity in structural design practice

摘要

This paper presents a view of the state of concrete plasticity as seen by a retired consulting engineer/structural designer. The author discovered the 'bimoment' method for the design of torsion-free Hillerborg slabs using upper bound collapse mechanism methods. He has also provided collapse mechanisms for plane-stress problems including shear in ordinary beams where longitudinal and transverse reinforcement may both be yielding.
