Kinetics of Drying Shrinkage and Creep: An Experimentally Based Code-Type Approachal environmental relative humidities. During the conditioning of the samples as well as during the execution of the creep tests, miniaturized humidity sensors were employed to measure the relative humidity in the concrete pores. The measured creep and shrinkage deformations are the higher, the highe潜伏期 发表于 2025-3-24 01:37:34

Finite Element Implementation of a Drying Shrinkage Model Based on Pore Evaporation Mechanicsoped a drying shrinkage strain model based on concrete microstructure, age and internal humidity. Validation of such a model provides insight into the validity of the assumed theoretical mechanisms. In this model, pore capillary tension is the main strain mechanism. Currently, application of the modsphincter 发表于 2025-3-24 14:13:33
Numerical Analysis of Long Term Effects on Eigenstresses and Micro-cracking in Concreteanalyses are therefore often carried out only taking into account the structure’s self weight and the other imposed loads. As a result, initial tensile stresses and (internal) cracking that can arise from, e.g., partially restrained shrinkage is not accounted for. This might imply that service lifeGrasping 发表于 2025-3-24 17:05:23
