It is essential to accurately describe the large shear behavior of woven fabrics in the composite preforming process. An analytical model is proposed to describe the shear behavior of fabrics with different weave patterns, in which tension-shear coupling is considered. The coupling is involved in two parts, the friction between overlapped yarns and the in-plane transverse compression between two parallel yarns. By introducing the concept of inflection points of a yarn, the model is applicable for fabrics with different weave patterns. The analytical model is validated by biaxial tension-shear experiments. A parametric study is conducted to investigate the effects of external load, yarn geometry, and weave structure on the large shear behavior of fabrics. The developed model can reveal the physical mechanism of tension-shear coupling of woven fabrics. Moreover, the model has a high computational efficiency due to its explicit expressions, thus benefiting the material design process.

“…The results showed that using CFRP sheets can increase the durability of RC columns after 600, 800 and 1000C. Some of the researches indicated the effect of extreme loading conditions in normal RC members and investigated any deterioration and defects inside or on the surface of the concrete (Goldston et al, 2016;Pham and Hao, 2016;Sayyar Roudsari et al, 2019a;2019b;2019c;2020a;Soleimani and Sayyar Roudsari, 2019;Tang and Saadatmanesh, 2003). However, different studies also undertook to find out the effect of HSC and high-performance materials under fire condition.…”

Reinforced concrete is one of the most common structures in the world. These structures may be under extreme loading conditions such as earthquake or they may confront with other flooding, impact or even the fire load. In the term of fire load, RC structures are very sensitive and due to the brittle behavior, the fast collapsing happens. In this research, two experimental setups are validated: (1) RC frame and (2) RC column. The Reinforced Concrete (RC) frame is modeled using finite element ABAQUS software and validated with experimental program. The RC frame validation is subjected to lateral and vertical loads. On the other side, RC column is also modeled and validated using ABAQUS software. The RC column is subjected to fire load. The results of validations show that the simulation techniques are accurate to perform the further investigation. The RC frames are retrofitted by FRP sheets and reinforced using steel or FRP bars. The angle of FRP sheets is both convergent and divergent. The fire is applied at the inside surface of the frame by 200, 400, 600, 800 and 1000C and lateral displacement-control load is considered, concurrently. Forcedisplacement diagrams have been evaluated to check the load capacity, ductility, stiffness, seismic factor and crack propagations. The results show that using FRP has better performance at the lower fire temperature.
