near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. it is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. this pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. in some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. theref...

We expound on the nature of collapse of one class of tall buildings (steel moment frame buildings) under earthquake excitation. Using a parametric analysis of a couple of index buildings subjected to idealized ground motion histories, we establish the ground motion features that cause collapse in these structures. Systematically mapping damage localization patterns, we track the evolution of th...

The particularity of cultural heritage and its interaction with the theme of energy efficiency has often been analysed either for the purposes of integrating climate control systems in listed buildings, which can be quite a complicated problem [ASHRAE, 2003] [CIBSE, 2002], or in the framework of the conservation of cultural heritage, using approaches which at times can be overly sectoral – [Tet...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...

This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...
