Seismic resilient structures using pre-cast pre-stressed concrete panels for modular construction

Abstract

Earthquake resiliency combined with sustainability can be achieved through state of the art technology and construction methods. In this paper, a new construction methodology is proposed for resilient and sustainable concrete structures. A resilient or Damage Avoidance Design (DAD) solution is proposed for pre-cast concrete rocking walls using a novel self-centring damper. A new procedure has been proposed to pre-stress the pre-cast concrete walls to reduce steel reinforcement, construction complexity and site work and consequently carbon footprint. First, the overall system configuration and lateral load performance is described. Then, the design steps of the proposed structural system will be discussed. The details of the construction methodology and applicability for modular construction is also presented in this paper. Finally, the performance of the proposed system is verified through experimental investigation.
