Seismic-Resistant Precast Concrete Structures: State of the Art

Abstract

Precast concrete facilitates a construction method using durable and rapidly erectable prefabricated members to create costeffective and high-quality structures. In this method, the connections between the precast members as well as between the members and the foundation require special attention to ensure good seismic performance. Extensive research conducted since the 1980s has led to new precast concrete structural systems, designs, details, and techniques that are particularly suited for use in regions of high seismic hazard. This paper reviews the state of the art of these advances, including code developments and practical applications, related to four different systems: (1) moment frames; (2) structural walls; (3) floor diaphragms; and (4) bridges. It is concluded from this review that the widespread use of precast concrete in seismic regions is feasible today and that the jointed connection innovation introduced through precast research leads to improved seismic performance of building and bridge structures.dividual papers.

Experimental and shear bearing capacity studies of the assembled composite wall with bolted connections

“…In the FP7 European project, numerous experimental projects were carried out to study the performance of different types of advanced connections, including a rebar connection and two types of steel mechanisms: Wall Shoe and steel plate. It shows that the ductility coefficient of the rebar connection and the Wall Shoe is close to 7, while that of the steel plate connection is lower due to the brittle failure of the bolts . To prevent slip and pinching caused by plastic deformation of the connectors, it is necessary to ensure that the design of connections is conservative .…”

“…To prevent slip and pinching caused by plastic deformation of the connectors, it is necessary to ensure that the design of connections is conservative . A new type of connection method for prefabricated wall has been introduced, and the experimental results show that the steel anchor bolts at the joint can be designed as the ductile structural fuses . The steel anchor bolts at the connection are designed as the ductile fuses to reduce damage to the concrete and minimize the loss of bearing capacity during an earthquake.…”

Experimental study of lateral load behavior of H‐shaped precast reinforced concrete shear walls with bolted steel connections

“…It allows mass production of standard components in a factory environment, thus leading to considerable reduction of the construction time and labor cost and better quality control . Precast RC structures with earthquake‐resistant connections and detailing are also popular in seismic regions …”

Full‐scale tests of precast concrete beam‐column connections with composite T‐beams and cast‐in‐place columns subjected to cyclic loading

“…In general, beam‐column connections in precast concrete frame structure can be broadly classified into two types, emulative and jointed (non‐emulative) . Emulative connections are designed and detailed to make the performance, in terms of strength, stiffness, and energy dissipation, of the precast concrete structures emulated to the monolithic cast‐in‐place (CIP) structures.…”

“…2,3 In general, beam-column connections in precast concrete frame structure can be broadly classified into two types, emulative and jointed (non-emulative). 4 Emulative connections are designed and detailed to make the performance, in terms of strength, stiffness, and energy dissipation, of the precast concrete structures emulated to the monolithic cast-in-place (CIP) structures. While, the jointed connections, which are distinctly different from emulative connections, allow nonlinear rotations of the structure deliberately concentrating at the ends of the precast members in the joint regions without causing significant inelastic behavior in the members.…”
