This paper presents quantitative information on the effectiveness of seismic retrofit solutions using bilinear oil dampers for seismically deficient existing tall steel buildings. For this purpose, a benchmark 40-story space moment-resisting frame building is studied that represents 1970s design practice in North America. Rigorous performance assessment based ASCE 41 recommendations reveals hig...

One of the most important problems discussed recently in structural engineering is the structural reliability analysis considering uncertainties. To have an efficient optimization process for designing a safe structure, firstly it is required to study the effects of uncertainties on the seismic performance of structure and then incorporate these effects on the optimization process. In this stud...

In this paper, the authors summarize the results of a parametric study devoted to evaluate the seismic behavior of low to medium rise regular special moment-resisting steel frames with hysteretic energy dissipation devices mounted on chevron steel bracing. For that purpose, 270 different building models were designed considering typical story heights and bay widths used in Mexican practice. The...

Resistance in the workplace, by nurses, has not been extensively studied from a sociological perspective. In this paper, nurses' resistance to the implementation and use of computer systems is described and analysed, on the basis of semistructured interviews with 31 nurses in three UK NHS hospitals. While the resistance was not "successful", in that it did not prevent the implementation of the ...

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation type timber–steel structure that incorporates prefabricated light wood-frame shear walls into steel moment-resisting frames (SMRFs). The such was evaluated through sh...
