Study on the Flexural Strength of Interior Thick Wall-Thick Slab Joints Subjected to Lateral Force Using Finite-Element Analysis

A brand-new structural type, termed thick wall-thick slab structure, has been developed in recent years based on the reinforced concrete wall structure Japan. This type of system can not only maintain high seismic performance, but also provide large interior space and improve flexibility architectural design that is more favored by architects. In present study, an equivalent cross-sectional area concept which a coefficient ratio proposed to estimate flexural strength horizontal member wall-slab joints, are critical assemblies structures. To capture stress condition reinforcement for calculating ratio, method finite-element analysis was employed this work. The modeling calibrated firstly using two isolated joints from literature consequently applied parametric numerical study. Finally, results these analyses adopted propose modifying current code formula predict TWTS structures subjected lateral force.
