Dataset on plastic and early-age shrinkage of ultra-high performance concrete with corresponding chemical shrinkage, temperature, relative humidity, reaction degree and material properties changes.

The data collected includes ultra-high performance (UHPC) shrinkage under sealed and unsealed conditions from 3 h after water addition, chemical shrinkage, UHPC internal temperature and relative humidity, Thermal gravity analysis (TGA) data, compressive strength, Poisson's ratio and elastic modulus of 9 UHPC mixes. UHPC early-age shrinkage was collected by a 250×250×100 mm mould and two linear variable differential transformers (LVDT) on the opposite positions and a sealing cover was applied to control the sealing condition of the top surface. Chemical shrinkage was measured by 500 mL Erlenmeyer flasks with a measuring pipette and paraffin oil was added to seal samples and indicate chemical shrinkage increment by liquid level change in the pipette.

Mechanics Model for Simulating RC Hinges under Reversed Cyclic Loading.

Describing the moment rotation (M/θ) behavior of reinforced concrete (RC) hinges is essential in predicting the behavior of RC structures under severe loadings, such as under cyclic earthquake motions and blast loading. The behavior of RC hinges is defined by localized slip or partial interaction (PI) behaviors in both the tension and compression region. In the tension region, slip between the reinforcement and the concrete defines crack spacing, crack opening and closing, and tension stiffening.
