Reinforced concrete (RC) jacketing of RC columns is used to increase the load-carrying capacity of RC columns with insufficient strength. The method of RC jacketing is an easy and cost-effective method. The confinement action is influenced by the stirrups in concrete core, stirrups in RC concrete jacketing, the thickness of RC jacketing, and the strength…
This present study addresses an assessment of effects on punching shear behavior and capacity of reinforced concrete (RC) slabs. The review on the punching shear capacity of the RC slab-column connection were conducted based on well-known literature. From the assessment, the concrete strength including concrete with steel fibers contributes sig-nificantly in the punching shear strength…
In many countries, and especially in Cambodia, there are many old structures, such as buildings and bridges, which are long-lived and will continue to deteriorate due to problems related to reinforced concrete (RC). One way to be able to delay or even prevent debt default is by anchor FRP. The experimental study of the effectiveness…
this case study presents the analysis of basic wind speed and serviceability evaluation of tall rein-forced concrete buildings under wind and earthquake in Phnom Penh. The objectives are to examine the basic wind speed in Phnom Penh and to compare the serviceability with earthquakes. First, the wind data collection from Phnom Penh Airport was analyzed…
For the renovation of concrete structures, a post-installed reinforcement system is used to connect the existing and new concrete structures. In that application, hole drilling is carried out into the existing concrete, and then the reinforcements are inserted into the holes with adhesive material. The reason to propose this study because of construction need to…
Fiber-reinforced polymer (FRP) anchors, also known as FRP anchors, are an emerging form of anchorage system to prevent or delay debonding of FRP from the concrete surfaces in the application of strengthening concrete structures using externally bonded FRP systems. This paper reports the results of experiments on Tyfo® Fibr anchors, which are made from glass…
Post-installed bundled reinforcement is used to connect the existing concrete with new concrete structures when the post-installed single reinforcement is not feasible. In this study, the assessment of the bond behavior of the post-installed bundled reinforce-ment is carried out using the finite element method (FEM). The study focused on evaluating the bond strength, and failure…
The aim of the research project is to study the behavior of system of steel roof components, which are made of suspended bendy rigid steel elements by a pole at each end. The elements of this type of roof system are subjected to tension and bending, and because it is lightweight and uncomplicated to build,…
This paper presents the analytical optimised truss model based on the principle of the minimum total strain energy theorem. The model was validated against 90 experimental data collected from the literature. The predicted shear strength in the analysis showed a very satisfactory correlation with the test results, with the average experimental/analytical failure load ratio of…
Two test series with various UHPC strengthening interventions were conducted in this study to investigate the behaviour of composite reinforced concrete (RC) slabs strengthened with UHPC. The first, RE series is a retrofit interventions, tested UHPC as patch material for repairing deteriorated concrete structures. As for the second, OV series is a UHPC overlay interventions,…
