Response modification factors (R-factor) are used in current seismic building codes to reduce earthquake forces associated with seismic design level to determine force levels. In recent years, many authors have shown great interest in the development of seismic structural systems and several theoretical and experimental studies have been conducted to investigate performance of dampers but littl...

road traffic crashes (rtcs) account for great mortality and morbidity rates worldwide, resulting in substantial global burden. factors contributing to rtc generally fall into three categories: environmental, vehicle, and human, with the human factor being by far the leading determinant. obtaining an in-depth exploration of driving behavior and factors underpinning risky driving could be of part...

background: safety programs are a core part of safety management in workplaces that can reduce incidents and injuries. the aim of this study was to investigate the influence of safety training observation program (stop) technique as a behavior modification program on safety climate in a construction company . methods: this cross-sectional study was carried out on workers of the petrochemical co...
