Efficient Numerical Analysis of Hybrid Shear Wall with Internal Energy Dissipating Reinforcements

Abstract

To ensure the structural safety, efficient performance, and minimums disturbance to business operations after an earthquake, proper seismic design of buildings is of ample importance. Often, post- tensioned (PT) shear wall having self-centering capacity is used as one of the effective ways of resisting large lateral shear force during earthquakes. However, to keep the structural form in serviceable condition, the maximum energy that can be dissipated through PT shear wall is limited to energy dissipation through the elastic behavior of PT tendons and pure rocking of the wall. Hence, in situations having a higher force and limited drift demand, PT shear walls with internal energy dissipating reinforcements (IEDR) are being used in practice. Analysis of such shear wall configurations though experiments is a tedious job and also not feasible for the economic point of view. Hence, there is a requirement of a computationally efficient numerical model that can replicate the actual behavior of post-tensioned (PT) shear wall with IEDR. The computational efficiency of the numerical model is also needed to be checked. This paper investigates the behavior of the numerical model of a PT shear wall with internal EDR subjected to lateral cyclic loading whose computational efficiency has also been examined and modifications are tried to be introduced. � 2024, Springer Nature Singapore Pte Ltd.
