Journal Title: International Journal for Computational Civil and Structural Engineering - Year 2017, Vol 13, Issue 1
Abstract
This paper provides detailed suggestions for process of modeling the structural reinforcement by composite materials on the software package "LIRA-SAPR". It provides the implementation of bearing capacity checks for reinforced elements on the program called "ESPRI". The article offers an algorithm for calculation the construction objects in case of the changing of design situation, taking into account the modeling of the composite structure reinforcement. It considers the modeling process of reinforcement of structures using classical methods, such as using of metal casing. In the article you can also find a numerical modeling example of the frame structure reinforcement, with the selection and verification of the composite material. It considered the process of modeling the bearing capacity increasing with using the classical methods, namely the increase of the metal hooping. The article investigates the example of a numerical simulation of the frame bearing capacity increasing with the selection and verification of the composite material. Using the finite element method a mathematical model of the frame structure was constructed. In the frame work it was taken into account the occurrence of the bearing capacity increasing by composite materials in some elements. It compared the kinematic characteristics and effort that have arisen within the frame design model with static analysis, also taking into account physical nonlinearity in the calculation and enhancing certain elements reinforced with composite material. Also in this paper we describe a method of modeling the bearing capacity increasing with using the metal hooping.The calculation of reinforced element is made on the program called ESPRI, followed by an analysis of the overall calculation model work on the software package "LIRA-SAPR". The result of the article is a comparison and analysis of the stress-strain state of the considered computational model for various problem formulations. The results could be used for wider application in the study of methods for increasing the bearing capacity of buildings and structures.
