Article
The case study is to explore the ditch cover with ultra-high-performance concrete (UHPC) and mainly focuses on seven different contents of steel fibers (0, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%) as variables. The fabrication of the UHPC ditch cover was performed with 60㎝×35㎝ ditch cover mold for UHPC casting and added wire mesh for 2 layers. The test parame...
Article
This study explores the reinforced concrete beams retrofitted with ultra-high-performance concrete (UHPC) or carbon fiber-reinforced polymer (CFRP). The main test items and methodologies are as follows: (i) Use basic mechanical tests to evaluate the feasibility of UHPC as a strengthening material. (ii) Probe into the retrofit effect of making small...

This study was to evaluate the CO2 curing on mechanical properties of Portland cement concrete. Three different specimen sizes (5 × 10 cm, 10 × 20 cm, and 15 × 30 cm cylinders), three CO2 concentrations (50%, 75%, 100%), three curing pressures (0.2, 0.4, 0.8 MPa), three curing times (1, 3, 6 h), two water cement ratios (0.41, 0.68) for normal and h...

Pervious concrete (also called porous concrete) is one of the most promising sustainable and green building materials today. This study examined high-strength pervious concrete and ordinary-strength pervious concrete reinforced with steel fiber or glass fiber. A total of fifteen mixtures of normal- and high-strength pervious concretes with steel fi...
Chapter
This clogging resistant study includes high strength pervious concrete (HSP) and normal pervious concrete (NSP). The HSP concrete aims to carry out 28-day strength above 42 MPa and porosity as close to 10% as possible to achieve the technical specifications. Some of the key tests were porosity, compressive strength, and permeability test. Experimen...
Chapter
This study was conducted to assess the effect of cylinder size on concrete compressive strength by CO2 curing. The factors studied to evaluate the effect of cylinder size on concrete compressive strength were cylinder size, CO2 concentration, curing pressure, curing time, and age of specimen at testing. Three different cylinder sizes (5 × 10 cm, 10...
Article
This study investigates the effects of steam and microwave curing on concretes containing fly ash, blast-furnace slag, or silica fume. Two steam curing treatments, four microwave curing times, and four types of concrete mix were used in this study. The test results indicated that microwave heating could further increase the compressive strength of...
Article
A design approach for strengthening reinforced concrete beams with externally bonded fibre reinforced polymer (FRP) laminates is proposed. The use of staggered FRP laminate bonding to the tension face of the beam is suggested as an economical design. The FRP development length suggested in the guidelines is adopted. It is recommended that the FRP U...
Article
Practical applications for the use of fibre reinforced polymer (FRP) composite materials for the seismic strengthening of reinforced concrete beams that have been constructed with a substandard beam bar termination method were experimentally investigated in this study. Results suggest that the cut-off reinforced concrete beam design does not meet t...
Article
The paper proposed a design method and an experimental programme to evaluate the axial load strength of rectangular and square reinforced compression members confined with GFRP (glass fibre reinforced polymer plates) jackets and steel hoops. Three square and three rectangular columns were tested under axial compression up to failure. The test resul...
Article
This study aims to use reactive powder concrete (RPC) as a new repair material and evaluate its bond durability to existing concrete. One accelerated aging environment, namely a freeze–thaw cycle acceleration deterioration test, was selected for the evaluation of bond durability of the repair materials. Before and after aging, the samples were eval...
Article
The results of an analytical and experimental study on the behavior of reinforced concrete T-beams retrofitted with carbon-fiber-reinforced polymer (CFRP) plates are discussed in this paper. CFRP plates were bonded to the underside of the beams with the main objective of increasing the service life load capacity. A test series comprising a prototyp...
Article
An analytical method for evaluating the short-term axial load deformation behavior of rectangular and square reinforced compression members confined with glass fiber-reinforced polymer plates (GFRP) jackets and steel hoops is proposed in this paper. Three square and three rectangular columns were tested under axial tension/compression up to failure...
Article
The target of the research in this paper is using truss analysis to predict the behavior of reinforced concrete moment-resisting frames, especially for the joints with poorly reinforcing details. The truss analysis is basically constructed by truss mechanism for a cracked RC frame. Parametric study for discussing concrete softened coefficients and...

Simulated seismic load tests on reinforced concrete one-way interior and exterior beam-column joints with substandard reinforcing details typical of low-rise buildings constructed in Taiwan are described. These substandard reinforcing details of the beam-column joints are mainly lack of transverse reinforcement and inadequate beam bar hooks bent ou...
