بایگانی برچسب: SSFRR concrete

Refractory concrete materials are widely used in high-temperature structural and industrial applications due to their excellent thermal stability, fire resistance, and durability under extreme environmental conditions. However, conventional refractory concrete exhibits inherent brittleness and limited tensile strength, which can lead to premature cracking and sudden failure under mechanical loading. To ...

In this example, an SSFRRC beam with a normal concrete outer layer, CFRP composite material, and steel bars as reinforcement is considered. To model the SSFRRC beam, the Concrete Damaged Plasticity model is used for the refractory concrete; the Johnson–Holmquist model is applied to the normal concrete; the Johnson–Cook hardening ...
