Thermal Strain and Drying Shrinkage of Concrete Structures in the Field

摘要: This article describes how substantial changes in temperature and moisture can occur when concrete structures are placed the field. In order to predict stress corresponding risks of thermal and/or drying shrinkage cracking, an estimate is required strain not related stress. this study, a proposed method was developed allow direct field measurement structures. A nonstress cylinder designed, which enabled embedded gauge measure actual Sensors, such as vibrating wire gauges relative humidity (RH) sensors, were incorporated into method. The validity investigated through laboratory tests well implementation. It expected that be efficiently used testing realistic assessments time-dependent behavior structures, including cracking potential.
