摘要: Shrinkage's influence on tension stiffening in flexure and subsequent short-term deflection effects beams slabs is investigated. Shrinkage can significantly affect initial response (particularly for laboratory-tested used to develop validate prediction theoretical models), although shrinkage typically thought of as a long-term effect. A shift the cracked transformed section's bare bar caused by taking place before beam loading locked into member response, resulting cracking moment reduction (caused tensile stresses that have developed due reinforcement restraint created concrete). Immediate (short-term) flexure-loaded increased when lower work together. perceived levels results, comparison experimental results with models also affected, this neglected.
