Abstract Buildings located on hill slopes are subjected to additional effects under seismic action compared with those flat ground. This article presents Incremental Dynamic Analyses of coupled building‐slope systems incorporating topographic amplification, nonlinear slope movement and irregular structural configuration hill‐side buildings. Two different stable slopes, supporting single multipl...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

The present article seek to investigate the function of elliptical steel damper function in steel frames seismic resisting. The elliptical damper is a kind of earthquake energy dissipater in structure which acts based on the steel yielding feature. Thus, this damper in frame lateral displacement mechanism is expected to have a satisfying hysteretic behavior in terms of energy absorption is on a...

in the aftermath of the 1994 northridge, california, earthquake. a significant number of steel moment resisting structural systems were damaged. many studies and researches have been conducted to improve the seismic performance of structures after the catastrophe. one of the proposed connections for special moment-resisting frames included aisc-358 is kaiser bolted bracket moment connection, br...

concrete beams reinforced with glass fiber reinforced polymer (gfrp) bars exhibit large deflections and crack widths as compared with steel reinforced concrete beams due to the low modulus of elasticity of gfrp bars. different studies show that aci 318 equation for the effective moment of inertia ie does not predict deflection well for frp reinforced concrete beams. the purpose of this paper is...

In Chile, office buildings are typically reinforced concrete (RC) structures whose lateral load-resisting system comprises core structural walls and perimeter moment frames (i.e., dual wall-frame system). the last 20 years, nearly 800 new have been built in country roughly 70% of them less than ten stories. Although seismic performance these was deemed satisfactory previous earthquakes, their a...

A cyclic loading test of a steel moment-resisting frame (SMRF) with nonstructural components was conducted to evaluate the seismic performance buildings subjected multiple earthquakes. The specimen is single-floor, one-span substructure intermediate story typical current middle- or low-rise building in Japan. Two specimens were tested. structural systems these two same, but attached different. ...

In the present paper, Fragility Curves (FCs) of Reinforced Concrete (RC) building types with moment-resisting frame structure representative existing Italian stock have been derived through an analytical approach. The proposed methodology is based on Non-Linear Dynamic Analyses encompassing all steps required to bring about reliable as well realistic fragility results. First, prototype selected...
