Reinforced concrete (RC) column is an important load-bearing component in building structures. In order to study the blast resistance of RC columns, numerical simulation model was verified based on field test data, and ANSYS/LS-DYNA 2020R2 software used expand working conditions. The sensitivity analysis method grey relation degree effects factors, such as diameter longitudinal reinforcement, n...

The test results on the performance of carbon fiber-reinforced polymer (CFRP)-confined reinforced concrete (RC) columns under axial compression load are presented in this study. Twelve slender CFRP-confined circular RC with a diameter 200 mm were divided into two groups. Six specimens different slenderness ratios 12, 20, 32, 40, 48, and 56 contained each group. experimental demonstrated circumf...

This study investigates the lateral impact responses of reinforced concrete (RC) and composite columns through dynamic nonlinear analysis using LS-DYNA. The simulation results were first validated against experimental performed earlier on four different cross sections. finite element show that LS-DYNA can predict well be used for further parametric analysis. overall resistance new is significan...

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

The main objective of this study is to investigate the effect of precorrosion and postcorrosion damage on concrete jacketed RC columns under uniaxial loading and to develop a rational methodology for predicting the corresponding compressive strength. The predamage and postdamage involved an electrochemical process to accelerate the migration of chlorides from an external electrolyte into the te...

This study investigated the response of reinforced concrete (RC) slabs in building structures to internal explosions. The performances of two slabs designed in accordance with the protective structural design and conventional gravity design approaches were evaluated in terms of midspan displacements, support rotations, and damage patterns. Data from available slab blast experiments in the open ...

Abstract Many existing structures show insufficient seismic capacity, with the lack of members' ductility being a critical factor. Aim is to manage increase their ductility, through confinement composite fiber reinforced polymer (FRP) sheets. In present paper, available analytical procedures Eurocode 8‐Part 3 (2005) and draft 2022 Greek Code for Structural Interventions (CSI) 2013 revision are ...
