An analog computation of carbon fiber-reinforced polymer (CFRP)-confined rectangular concrete column under cyclic lateral load is carried out using the finite element method (FEM) and is compared with the experimental results. The comparison indicates that the FEM could accurately predict the behavior of CFRP-confined reinforced concrete (RC) column under cyclic lateral loading. The reinforcement mechanism of carbon fiber sheets on RC columns is studied by analyzing the results calculated with FEM such as the stress-strain of carbon fiber sheets, stirrups, and concrete. The effect of axial compression ratio and the number of layers of fiber sheet on the ultimate bearing capacity and displacement ductility of RC column are studied by the finite element analysis. Part of the conclusion, namely, the effect of the number of layers and setting height of fiber sheet on the RC column, offers the reference and basis for further engineering application. template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.

5) Though a traditional material used for construction for ages, masonry is a complex composite material, and its mechanical behavior is influenced by a large number of factors, is not generally well understood. This research aims to study the methodology available in the literature to evaluate the increase in performance of masonry by applying different reinforcement options under in-plane lateral loading. Nonlinear static analysis has been carried out as part of this research to achieve the above objectives. Different unreinforced masonry wall panels were analyzed at various load conditions. Material properties for the masonry wall were taken from the experimental test results of previous literature. The walls were first checked for two failure mechanisms. The stress distributions of walls were checked in each step of analysis and shear failure, and rocking failure was found. Each wall was then analyzed for six different reinforcement options. The comparison of results obtained from the reinforced wall analysis with that of the unreinforced wall indicated significant increase in lateral load-bearing capacity and decreased wall displacement with reinforcement. The maximum increase in load-bearing capacity was achieved by adding chicken wire mesh or CFRP bands throughout the wall while the maximum decrease in displacement was achieved by adding 12 mm diameter bars at the spacing of one meter.

The main focus of this paper is to describe the behaviour of RC columns that are retrofitted with an alternative technique to “jacketing” or wrapping. This new technique consists of attaching steel plates to the flexural faces of a concrete column using bolts. It is envisaged that this technique would be suitable primarily for columns having rectangular cross-sections and in situations where lateral loading induces predominately a single plane of bending (as opposed to biaxial bending). Effectiveness of this new technique has been demonstrated by experimental testing and numerical simulations. This paper studies the mechanism of the new retrofit scheme, how it works, and the behaviour of columns retrofitted using such a scheme, as well as the important parameters that affect the response of the retrofitted columns. This study forms the basis for the design of the plate retrofitting system.
