The effect of aftershocks on the fragility single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models an unreinforced (URM) structure and a confined (CM) are established their response characteristics when subjected to mainshock, aftershock, mainshock-aftershock sequence then comparatively investigated. effects use confining members studied...

A tuned mass rocking wall (TMRW)-frame structure system is proposed to improve the energy dissipation ability of traditional wall-frame system. Based on principle damper (TMD), a TMRW designed with proper and stiffness according dynamic characteristic host structure. Firstly, considering presence inherent structural damping, amplification factor main was derived from equations mechanism. practi...

This study examines the influence of pressure tap density and layout on estimated wind effects a 47-story steel building for which Database-Assisted Design procedure is used to calculate base shears, overturning moments, member Demand-to-Capacity Indexes (DCIs), inter-story drift ratios, floor accelerations. From an original (20 rows by 5 columns, total 100 taps per façade), 16 cases were creat...

In this work, a tied braced frame (TBF) was developed to achieve uniform inelastic deformation in an eccentrically (EBF) by connecting links across the entire height with tie members. Herein, TBF design method is proposed, considering new lateral force distribution pattern. To better evaluate seismic performance, and verify advantages of TBF, nonlinear time-history analysis fragility were condu...

Large changes in stiffness associated with cracking and yielding of reinforced concrete sections may be expected to occur during the dynamic response of reinforced concrete frames to earthquake ground shaking. These changes in stiffness in stories that experience cracking might be expected to cause relatively large peak interstory drift ratios. If so, accounting for such changes would add compl...

344 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Abstract— Orthogonal frequency division multiplexing (OFDM) is very sensitive to frequency offset caused by Doppler frequency drift or frequency drift between transmitter and receiver oscillator. This leads to a loss in the orthogonality between sub-carriers and results in inter-carrier-interference (ICI). In ...

Abstract The modern design and construction of buildings have led to the adoption irregular shapes which can attract large seismic forces induce stress concentrations in building itself. To investigate this fact a number research studies been carried out. This study presents review summary performance considering vertical irregularity subjected earthquake loadings. be found by using linear nonl...
