Computational methodology to determine the strength of reinforced concrete joint

摘要: Seismic performance of structures depends on the force flow mechanism inside structure. Discontinuity regions, like beam-column joints, are often affected during earthquake event due to complex and discontinuous load paths. The evaluation shear strength identification failure mode joint region helpful (i) define hierarchy sub-assemblage, (ii) quantify influence different parameters behaviour and, (iii) develop suitable adequate strengthening scheme for if required, obtain desired hierarchy. In view this, it is very important estimate identify modes as most critical part in any sub-assemblage. One effective models softened strut tie model which was developed by incorporating equilibrium, strain compatibility constitutive laws cracked reinforced concrete. this study, model, incorporates equilibrium equations, conditions material relation concrete, used simulate mechanisms joints. observations present study will be arrive at design strategy joints ensure achieve sustainability structural systems under seismic loading.
