Performance of IBS Precast Concrete Beam-Column Connections Under Earthquake Effects: A Literature Review

Abstract

Problem statement: Despite demonstrating rather much benefits comparing to the conventional cast-in-place construction, the acceptance level of precast concrete building is still reportedly low in Malaysia. The implication imposed by stricter seismic design provisions would only worsen the matter. Approach: The main objective of this study was to identify the most appropriate type of beam-column connections to be introduced to precast concrete industry, particularly for regions of low to moderate seismicity. Hence, this study presented a comprehensive literature overview of the findings from studies conducted to analyze and investigate the behavior of precast concrete systems assembled with typical connections or joints under simulated earthquake loading. Results: The seismic performance of precast concrete structure very much depended on the ductility capacity of the connectors jointing each precast components, especially at critical joints such as the beam-to-column connections. It was learnt from the review that (1) hybrid post-tensioned beam-column connection and (2) Dywidag Ductile Connector® were among the most widely used connectors for precast construction in seismic prone regions. Conclusion: Future refinement and research could be carried out in order to optimize these connections to be used in low seismicity regions. Proposed connection type should be practical and well-accepted to avoid further impediment of the precast system.

Factors Affecting Vulnerability of Ready-Made Garment Factory Buildings in Bangladesh: An Assessment Under Vertical and Earthquake Loads

“…Our marginal effect analysis demonstrates that a one-unit increase in internal frame irregularity increases the earthquake load vulnerability of factory buildings by 0.047 (Table 2). This result is consistent with the findings of Yee et al (2011) where the authors mentioned that a regular column grid is a prerequisite for seismic resistance. An irregular internal frame has moderate correlation with earthquake load vulnerability (correlation value: 0.409; Table 4).…”

“…Buildings with an irregular internal frame are subjected to torsion, instability, and localized damage (FEMA 2006). They also behave poorly under earthquake load (Yee et al 2011).…”

Experimental and numerical studies on design for deconstruction concrete connections: An overview

“…On the other hand, a good understanding of current state of the art through a comprehensive review of available literature could present an opportunity to coordinate future research directions to address the key issues and barriers hindering the widespread application of DfD systems in practice. While a number of efforts has been made to review the state of the art in generic types of connections used in precast concrete (Nakaki et al, 1999; Priestley, 1996) or engineering applications (Jaillon and Poon, 2014; Yee et al, 2011), such studies tend to focus on conventional connections without discussing their demountability and suitability for DfD structures. There is currently a lack of comprehensive review of recent development with regard to DfD connections.…”

Experimental investigation on a non-seismic precast RC beam-column exterior joint under quasi-static lateral cyclic loading

“…Precast structure seems to be more practical nowadays to overcome problems pertaining construction productivity and the quality of construction products, despite the shortage of skilled workers [6]. Precast concrete framed structures were more popular as compared to prefabricated steel framed structures due to price matters even though steel structures are relatively lighter in mass and lacking in stiffness [7]. Precast concrete products are widely adopted in Malaysia started in the year between the 1960s and 1980s, due to the rising demand from public housing projects including of low and medium cost apartments [8].…”
