A large wall with vertical cracks at mid-span, varying in width of up to 3 mm wide, had been declared capable of resisting a postulated seismic load. It was not straightforward to subsequently confirm, analytically, what influence the crack had on the wall’s capacity for lateral loading. It was assumed that it was likely that the horizontal reinforcement had yielded across the crack and thus th...

• Bare steel and composite semi-rigid moment-resisting connections were tested. The comprised CFS tubular sections connected using side plates. Various failure limit states captured through the tested connections. infill concrete effectively prevented beam local buckling. Side plate plasticity considered as a desirable energy dissipation mechanism. This paper presents results of full-scale phys...

External installation of steel braces is an effective approach to increase the lateral load resistance moment-resisting frames. However, effects existence on robustness frames resist progressive collapse still not clear because little study has been carried out. To fill this gap, in paper, six multistory subframes (three bare and three braced frames) were fabricated tested. Test results indicat...

Good sleep habits and effective self-control are important components of successful functioning. Unfortunately chronic sleep loss and impaired self-control are common occurrences for many individuals which can lead to difficulty with daily self-control issues such as resisting impulses and maintaining attentive behavior. Understanding how self-control is depleted and how good sleep habits may h...

Horizontal stirrups are normally required in reinforced concrete (RC) beam-column joints (BCJs) for resisting shear forces seismic design. For RC moment-resisting frames subjected to a high lateral load, large number of needed joint cores. This may cause reinforcement congestion, leading construction difficulty and insufficient compaction, which can result poor performance. In this study, novel...
