“…The SD685 and SD 785 rebar were originally developed in Japan and modified slightly in Taiwan by TCI New High-Strength Reinforced Concrete Committee [1]. Experimental study using high strength concrete and high strength steel on reinforced concrete columns was performed by Hwang et al [2], Ou and Kurniawan [3,4], Ou et al [5], and Liao et al [6]. All these experimental researches studied the behavior of high-strength reinforced concrete columns subjected to flexure and shear behavior.…”

In high-rise buildings, the column has a vital role in resisting gravity and earthquake load. The utilization of highstrength concrete and high-strength steel rebar in high-rise buildings can reduce column dimension at lower storeys. In this study, Nonlinear Finite Element was carried out to model the flexure behavior of high-strength reinforced concrete columns subjected to displacement-controlled monotonic loading and constant axial loading. Two concrete columns specimen were modeled using a 3D finite-element analysis. Two-level of axial compression load was applied, as representative of low and high axial load columns in high-rise buildings, respectively. The columns were utilized with high-strength longitudinal reinforcement, high-strength transverse reinforcement, and high concrete compressive strength. Finite element analysis was carried out with appropriate material constitutive concrete and steel, geometric modeling and mesh. The finite element analysis result showed that the prediction of force-drift relationship curves is relatively similar to the experimental result.

Mechanical reinforcement couplers can offer considerable constructional and economic advantages in comparison with conventional methods of lap splicing, particularly when the requirements for seismic detailing exacerbates reinforcement congestion problems. However, the lack of specific codified guidance on ductility considerations hinders the application of mechanical couplers under inelastic conditions. To this end, this brief paper provides an overview of various reinforcement coupling systems, as well as a comparative assessment of their 'in-air' and 'in-concrete' performance, based on results extracted from a collated database. The main behavioural characteristics of different coupler forms are discussed, and their key performance parameters are compared. In addition to strength and ductility, the influence of the coupler size and arrangement on the ductility of structural members is discussed. The comparative assessments presented offer some guidance for the selection and application of mechanical reinforcement couplers in inelastic regions, and highlights areas in which further detailed investigations are required.

A simulation method with Abaqus software was adopted to analyze the seismic performance of post-fire precast concrete column with grouted sleeve connections. First, the simulation was exerted on the column at ambient temperature and the grouted sleeve connection was simplified to be a single steel rebar. It is found that the yield load, lateral peak load and ductility coefficient from the simulation result are about 0.89, 0.85, and 1.02 times of those from the test respectively, which shows that the built finite element model is fit for the simulation analysis of precast concrete column and the simplified method of grouted sleeve connection is feasible. Then, a sequential coupling method was used to simulate the seismic performance of cast-in-place column after exposure to elevated temperatures. It is found that the highest temperature, load and ductility coefficient from simulation agree well with those of test, as the maximum difference is only 5.0%. Furthermore, simulations of post-fire precast concrete columns with grouted sleeve connections were based on these practices and the findings as follows: as the elevating time becomes longer, the maximum difference of the highest temperature between the simulation and the theory decreases from 6.7% to 0.6%; compared to the condition at ambient temperature, the lateral peak load decreases linearly along with the elevating time ascending. Finally, a new expression was proposed to calculate the shear bearing capacity of post-fire precast concrete column with grouted sleeve connections, which will be beneficial to the fire safety design of precast concrete structures.
