Analysis of Tunnel Form Building Retrofitted with CFRP using Finite Element Method

Abstract

Many regions where have the earthquake risk around the world, many buildings in developing countries are ineffective in front of earthquake forces. Recent years, the fabrics which are strengthening with carbon fiber-reinforced polymer (CFRP) have become a very common material to strengthen the reinforced concrete buildings. In our country, mostly column jacketing and partition systems are used. They are also followed with steel jacketing and trussed steel joist systems. Reinforcement with composites named FRP (fiber-reinforced polymer) are getting common slowly by slowly in our country. Since fibers are hightensile steel, they increase the strength of joist and covering deflection. If it is used in the direction of tensile, it also saves the strength for shearing. In this study,1 mm CFRP hardware is applied to the each covering of a 16-floor reinforced concrete building which is made with tunnel formwork system. In this analysis done with SAP2000 program, increase in the frequency of a reinforced concrete building is observed; structure which has less in cycle is appeared. These results show us that CFRP hardware's make and %38 increase in the rigid of structure.

Çelik Bina Modellerinin Kolonlarında Molibden Profil Kullanımının Modal Parametrelere Etkisi

“…It is known that the finite element method is widely used in academic studies. With the finite element method, [23][24][25][26][27][28] studies were used in the modeling and analysis stages. In order to comparatively investigate the effect of molybdenum profile usage on modal parameters, a steel structure model consisting of steel columns and a steelmolybdenum structure model consisting of molybdenum columns were created.…”
