Assessment of the Effects on Punching Shear Capacity of RC Slabs

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…

Experimental Study of the Effectiveness of Fibr Anchors Inserting into Concrete Cylinder Confined by Glass Fiber Reinforcing Polymer

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…

Basic wind speed analysis and serviceability evaluation of tall reinforced concrete building subjected to wind and earthquake: a case study in Phnom Penh

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…

Bond Strength Assessment of Post-Installed Single Reinforcement using Finite Element Analysis

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…

Assessment of Bond Behavior of Post-Installed Bundled Reinforcement using Finite Element Method

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…

Prediction the Shear Strength for FRP Shear Strengthened RC Beams Based on Optimised Truss Models

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…

Retrofitting and Strengthening Interventions of RC Members Using Ultra High Performance Concrete (UHPC)

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,…
