Project: Local Degree of Freedom Ductility Demand
Ductility demand during an earthquake has long been known to be a good measure of structural damage in buildings during earthquakes. For design purposes it is considered a priori according to some rules that may or may not apply to each building. Such ductility parameters are mostly based on the response of a single degree of freedom system to ground motions. However, it has been probed that th...
متن کاملFormulation of design eccentricity to reduce ductility demand in asymmetric buildings
A critical analysis of the large number of papers about the seismic behaviour of asymmetric buildings shows some concordant results: the modal analysis correctly predicts their elastic dynamic response to seismic records, while it overestimates deck rotation in the inelastic range. On this basis, the authors propose to design asymmetric structures by twice repeating the modal analysis: the firs...
متن کاملInvestigation of the Distribution of Cumulative Ductility Demand Parameter in Various Storeys of Buckling Restrained Braced Frames
Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...
متن کاملApproximate Dynamic Analysis of Structures for Earthquake Loading Using FWT
Approximate dynamic analysis of structures is achieved by fast wavelet transform (FWT). The loads are considered as time history earthquake loads. To reduce the computational work, FWT is used by which the number of points in the earthquake record are reduced. For this purpose, the theory of wavelets together with filter banks are used. The low and high pass filters are used for the decompositi...
متن کاملCross section reconstruction during uniaxial loading
The inelastic response of materials to applied uniaxial loading is typically measured using tensile or compressive specimens of initially circular cross-section. Under deformation, this cross-section may become elliptical due to anisotropic material behaviour. An optical technique for measuring the elliptical deformation of anisotropic, homogeneous cylindrical specimens undergoing uniaxial defo...
