Precast Steel-Reinforced Concrete (PSRC) structural frame systems for moment-resisting, comprised of Prefabricated Steel (S) girders and Reinforced Cement (RCC) columns. This system has the advantage inherent stiffness damping during a seismic event. PSRC’s moment-resisting is also known its construction efficiency, lightweight, low cost. Earlier investigations have shown PSRC helpful in design...

Steel plate shear walls (SPSWs) are one of the most economical and under-utilized lateral load resisting systems currently available to structural engineers. In comparison with traditional lateral load systems, such as steel braced frames, reinforced concrete walls and moment resisting frames, SPSWs have fewer costly detailing requirements, require less stringent construction tolerances, allow ...

This paper introduces a novel design concept for the development of efficient, sustainable Rocking-Wall Moment Frames (RWMFs) under seismic conditions. The proposed concepts lead to a novel structural configuration with provisions for Collapse Prevention (CP), Self-Centering (SC), reparability, performance control (PC), damage reduction, and energy based seismic analysis. It introduces the meri...

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...

A residential building with a lateral load resisting system, adopted as a reference example, is considered in the paper. The system is made of shear walls realized using the tunnel form technology. The building is modelled for a varying number of floors, and the model is also used to consider the applicability of the technology with regard to construction costs. The influence of the type of soi...

Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...

The outrigger truss system is one of the most frequently used lateral load resisting structural systems. However, little research has been reported on the effect of installation of outrigger trusses on improvement of lateral stiffness of a high-rise building through full-scale measurements. In this paper, stiffness changes of a high-rise building due to installation of outrigger trusses have be...
