ABSTRACTMost of the steel moment resisting frames, damage at the beam-to-column connections during seismic loads. Application of passive dampers in order to prevent damages to the main components of structure has been an interesting subject for many researchers recently...

Over the recent years, different damage indices have been to predict the building damage, each of which uses different parameters to model the building damage. In this paper, 27 frames containing 18 frames with lateral load resisting systems of thin-steel shear wall typ...

The shortcoming of loose sandy soils in terms of shear strength besides placement of a huge number of structures on them drive the critical requirement for exploring the shallow foundations treatment, their positioning and shapes. In this regard, stabilization of loose ...

Mortar is suitable for utilizing in compressed parts such as columns and arches due to its considerable compressive strength. However, despite this advantage, the relatively low tensile strength and brittleness of the mortar limit its use for components that are under t...

In risk allocation process, it is not correct to pass the whole responsibility of some risks to the contractor. The reason is that some defensive strategies such as lowering the work quality and lodging claim and litigation may be implemented by the contractor that may ...

Due to the 1994 Northridge earthquake, many of welded steel moment resisting frames (WSMRF) collapsed in the connection area of the beam to a column. The damage in WSMRF, which was contrary to the expectations of the engineers, changed the attitude of the WSMRF. Thus, e...

Construction of large-scale structures has been considered as one of the human's main achievements. With their suitable view and high economical aspects, High-strength steel cables have been developed for analysis and erection of cable-stayed bridges in light of high sp...

Hardened concrete due to brittleness, have low tensile strength and its strain tolerance is low. Low resistance of this material makes it more brittle. Light weight concrete which contains eager and brittle materials are subject to sudden failure at the time of loading....

Buildings during their useful life may be affected by different external threats. These threats can harm the key elements of buildings and thus lead to progressive collapse. In recent decades, researchers have been working extensively on how to deal with abnormal events...
