Improving of Damping Character of Chimney by Modified Concrete under Seismic Load
Author:
Abstract: As known concrete exhibits weak behavior on damping character and ductility. Effective nature disaster such as earthquakes largely affects structures as horizontal axis and cause deformations. As a result of deformations, fractures in the structure may be observed. Even, fractures may cause the collapse of structures. Based on this problem, damping and ductility properties improvement of engineering structures is significantly necessary. Rubber material demonstrates high ductile features under load. Particularly, it is used for the reduction of vibration in mechanical systems. In literature, some experimental research focused on utilizing rubber for concrete production, and several properties such as damping ratio and young modulus were investigated. In ,these numerical analyses, young modulus, compressive strength, and damping ratio properties of concrete-modified rubber fine aggregate from selected experimental research were assigned to finite element method (FEM) software and were realized numerical analyses of chimneys. Results reveal that Rubber incorporation causes increasing in accelerations. However, increasing ductility behavior and greater damping energy absorption are concluded.
