Behavior of conventional and fibered concrete shear walls during earthquake, an analytical simulation in SAP2000

The investigation of this paper was about non-liner behavior of shear walls against seismic wave by using conventional and fibered concrete. Case of earthquake study was Iripina 1980, Italy with Ms = 6.9 and fourth kind of shear walls with glass fiber, basalt fiber, steel fiber concrete and conventional concrete shear walls simulated in SAP2000 with dynamic analysis method. Analysis shows that glass fiber concrete and conventional concrete shear walls had similar behavior, also these shear walls had more suitable response. All shear walls behavior were same at the beginning of earthquake but at the end of earthquake basalt and steel fiber concretes had a lot of displacement. Furthermore, behavior of steel fiber concrete shear wall could not return at the last moments of earthquake. Beside modulus of elasticity and compressive strength had most effect on reaction of shear walls such that modulus of elasticity was the cause of doing linear behavior of shear walls during all times of earthquake, on the other hand compressive strength had most efficiently in dissipation energy. Best result in earthquake was with conventional concrete due to modulus of elasticity and compressive strength. © Published under licence by IOP Publishing Ltd.
