Abstract

The accurate calculation of restrained stress is crucial for assessing the cracking risk in concrete structures. However, existing methods often lack precision in accounting for in-situ creep during the cracking process, thereby affecting the reliability of stress predictions. This paper introduces methods for calculating the restrained stress of Ultra-High Performance Concrete (UHPC) considering in-situ creep measurements. Firstly, novel molds, loading devices, and test methods are proposed to efficiently acquire long-term creep data of UHPC. In addition, the compressive and tensile in-situ creep behavior during the cracking process were characterized using an improved Temperature Stress Testing Machine…
