Description
Precast concrete structures are becoming one of the most popular constructions in the world. They are expected to lead the global construction because they are fast, cheap and simple to construct with precast concrete elements produced in tightly controlled conditions. Moreover, they are sustainable products with high durability. Minimal waste is produced during manufacture and precast elements can be fully recycled at the end of their life. In this paper, a Performance Based Design (PBD) approach is proposed for multi-storey precast concrete frame structures. A full review of Direct Displacement Based Design (DDBD) methodology to design precast concrete structures is carried out. A hybrid connection consists of unbonded post-tensioned tendons and conventional steel is suggested to connect beams to columns. In this connection, the inelastic behaviour of steel is used to dissipate the seismic energy and the unbonded post-tensioned strands are used to self-centre the structure after the seismic event. The post-tensioned tendons are suggested to be placed at the middle of the beam inside ducts without filling them with grout to avoid bonding between the tendons and the concrete. The future testing plan of one storey precast concrete structure with hybrid connections at the shake table test facility at UET Peshawar will be illustrated.
