The response of a steel moment resisting frame (MRF) depends on the specifications of its main components, namely the columns, beams and connections. One important connection element which can significantly affect frame behavior is the panel zone (PZ). The PZ is described to be an element mainly subjected to shear stresses and its failure mode is often governed by shear yielding. Several analyt...

A case study of retrofitting a 20-story pre-Northridge steel moment-frame building is presented. Twelve retrofit 4 schemes are developed with varying degrees of intervention. Three retrofitting techniques are considered: up5 grading the brittle beam-to-column moment resisting connections, and implementing either conventional or 6 buckling-restrained brace elements within the existing moment-fra...

This paper presents the application of the harmony search based algorithm to the optimum detailed design of special seismic moment reinforced concrete (RC) frames under earthquake loads based on American Standard specifications. The objective function is selected as the total cost of the frame which includes the cost of concrete, formwork and reinforcing steel for individual members of the fram...

Modular structural systems are constructed using a method that they are assembled with prefabricated unit modular frames on-site. This provides a benefit that can significantly reduce building construction time. The structural design is usually carried out under the assumption that their load-carrying mechanism is similar to that of traditional steel moment-resisting systems. However, both syst...

Israeli non-governmental organizations (NGOs) resisting the security fence and other Israeli security measures are in ‘virtual isolation’ in networks dedicated to the Palestinian-Israeli conflict, and especially to the criticism of Israeli governmental policies and the construction of the security fence.The research reported is a hyperlink and term analysis of select issue networks on the Web a...

The present study explored whether and how self-injurers attempt to resist urges to harm themselves. Participants were 39 young adults with a history of skin cutting and other non-suicidal self-injurious behaviors. A structured interview assessed the prevalence and perceived helpfulness of 48 methods for resisting self-injurious urges. Ninety percent of participants indicated that they had made...

In design steel frames, combining semi-rigid and rigid connections can result in better structural performance, particularly seismic locations. this study, the effects of beam-to-column located on performance frame structures are investigated. The analysis uses six twelve-story moment resisting frames (MRSF) with rigid, semi-rigid, dual beam-column connections. These designed according to Egypt...
