Alternate load paths in mitigating progressive collapse of RC building structures subjected to column loss scenarios
Tan, Kang Hai; Yu, Jun; Pham, Xuan Dat (2010)Column loss scenarios result in high potential for progressive collapse of RC building structures since the gravity loads are severely amplified by both doubling-of-span and dynamic factors. Under such a situation, tensile ... -
Analytical Model for Compressive Arch Action in Horizontally Restrained Beam-Column Subassemblages
Kang, Shao-Bo; Tan, Kang Hai (2016)This paper presents an analytical model to predict the compressive arch action (CAA) of reinforced concrete beam-column subassemblages. In the model, a new method is proposed to quantify the strains of longitudinal ... -
Analytical model for the capacity of compressive arch action of reinforced concrete sub-assemblages
Yu, Jun; Tan, Kang Hai (2014)Compressive arch action (CAA) is a favourable structural mechanism to mitigate progressive collapse of reinforced concrete (RC) frames. To quickly and accurately predict the CAA capacity of RC sub-assemblages under a ... -
Analytical model on the bond stress-slip relationship between steel reinforcement and concrete for RC beam-column joints
Long, Xu; Tan, Kang Hai; Lee, Chi King (2013)There are no conventionally accepted failure criteria for progressive collapse, and often times, deflection of affected beams over the “missing column” are often used as performance criteria. However, when simulating the ... -
Application of Engineered Cementitious Composites to Precast Beam-Column Sub-Assemblage under Column Removal Scenarios
Kang, Shao-Bo; Tan, Kang Hai; Yang, En-Hua (2015)This paper presents an experimental study on the behaviour of precast beam-column sub-assemblages under middle column removal scenarios. By using Engineered Cementitious Composites (ECC) in the beam-column joint and the ... -
Bar stress-slip relationship in reinforced concrete joints with large inelastic bar strains
Yu, Jun; Tan, Kang Hai (2012)Experimental results indicate that for reinforced concrete (RC) members under large deformations, such as catenary action, wide cracking and severe concrete crushing are concentrated at the beam-column connections. Bar ... -
Behaviour of different types of steel connections in steel frames against progressive collapse
Tan, Kang Hai; Yang, Bo (2012)Firstly, this paper presents an overview of DoD code [1] against progressive collapse and points out the shortcomings of the current design approaches. After that, seven experimental tests of common types of bolted steel ... -
Behaviour of precast concrete beam-column sub-assemblages subject to column removal
Kang, Shao-Bo; Tan, Kang Hai (2015)Under column removal scenarios, initiation of alternate load paths via adjacent bridging beams to redistribute vertical loads requires certain level of ductility and continuity in beam–column joints. Although this approach ... -
Bond stress-slip prediction under pullout and dowel action in reinforced concrete joints
Long, Xu; Tan, Kang Hai; Lee, Chi King (2014)When analyzing reinforced concrete (RC) framed structures under monotonic loading—for example, progressive collapse and pushover analysis—besides flexural deformation, the so-called “fixed end” rotations induced by ... -
Bond–slip behaviour of deformed reinforcing bars embedded in well-confined concrete
Kang, Shao-Bo; Tan, Kang Hai (2016)Precast concrete beam–column sub-assemblages may exhibit pull-out failure of reinforcing bars embedded in the middle joint when subjected to column removal scenarios. This failure mode has to be considered in analytical ... -
A case study on the evacuation of deep mega underground development in Singapore
Ng, Yan Hao; Nguyen, Minh Phuong; Tan, Kang Hai; Ng, Kian Wee (2017)Subterranean space utilisation is considered as a viable solution to the lack of land space in Singapore. However, commercial development, with substantial floor area located at a significant depth underground is the ... -
Development of compressive arch action in reinforced concrete sub-assemblages
Yu, Jun; Tan, Kang Hai (2012)Compressive arch action (CAA) of reinforced concrete (RC) members is a beneficial structural mechanism to mitigate progressive collapse of RC framed structures without any additional cost. CAA relies on the restraints at ... -
Discussions on design of precast prestressed planks and biaxially-loaded slender columns using EN 1992-1-1:2004
Tan, Kang Hai; Nguyen, Tuan Trung; Nguyen, Thruong Thang (2012)The first part of the paper presents a comparison of prestressed plank design at serviceability limit state between BS 8110 and EN 1992-1-1:2004 (EC2). While for the ultimate limit state design there is no considerable gap ... -
Effect of partial debonding on catenary action of reinforced concrete frames
Yu, Jun; Tan, Kang Hai (2012)Progressive collapse resistance of buildings can be evaluated by introducing a middle column removal scenario to mobilize alternate load paths (ALP). Catenary action, one of ALPs, uses tensile force in beams to balance ... -
Effect of unprotected interior beams on membrane behaviour of composite floor systems in fire, I : experimental investigation
Tan, Kang Hai; Nguyen, Tuan Trung (2013)A number of previous studies on tensile membrane action have been conducted and they are very valuable towards understanding the behaviour of isolated slabs as well as of floor assemblies. However, the role of unprotected ... -

Xu, Jin; Lee, Chi King; Tan, Kang Hai (2013)A 6-node triangular Reissner-Mindlin plate element with eXtended Finite Element Method (XFEM) formulation for yield line analyses is presented. The XFEM formulation with regularized enrichment is employed to reproduce a ... -
Experimental and numerical evaluation of FRP-retrofitted RC structure behavior under blast loading
Yi, Na-Hyun; Tan, Kang Hai; Kim, Jang-Ho Jay (2014)Generally, concrete is known to have a relatively high blast resistance compared to other construction materials. However, some existing concrete structures require retrofitting during their service life to improve their ... -
Experimental study on catenary action of RC beam-column subassemblages
Yu, Jun; Tan, Kang Hai (2010)Catenary action is considered as the last defense of a structure to mitigate progressive collapse, provided that the remaining structure after an initial damage can develop alternate load paths and a large deformation has ... -
