Special concentric braced frames are provided in buildings located in severe seismic zones
to resist earthquake loads. The seismic performance of these frames is mainly depend on …

For a braced frame it is important to understand the relationships between the lateral
stiffnesses, internal forces and bracing patterns in order to achieve an efficient design. This …

This paper reports the results of an investigation on the use of Generalised Beam Theory
(GBT) to analyse the vibration behaviour of thin-walled steel frames. After an overview of the …

Steel cable with its superior performance is used in steel structure as a brace. An X-
deployed cable-braced bolt-assembly steel frame (CBBSF) was proposed. The seismic …

Tower cranes, which are composed of a lattice structure, are mostly used to transport heavy
materials and equipment in construction sites. The delicate structure of tower cranes and …

In this study, the effects of three different viscous damper configurations, chevron, diagonal
and toggle, as well as brace stiffness on the performance of brace-viscous damper system in …

In the past few decades, multi-story X-braced frames have frequently been used to retrofit
RC buildings and have become the subject of more attention and implementation to improve …

It is very common to encounter structures having re-entrant corners. These types of
structures are very prone to damage under earthquakes. Bracings placed in different …

Steel bracings are among the most common and potentially effective technical solutions for
enhancing the seismic safety of existing reinforced concrete structures. Nevertheless …

It is very important to know the dynamic behavior of base slabs of buildings in earthquake
prone areas. The slabs are generally assumed as a rigid diaphragm in structural analysis …
