post failure analysis of massive structure infers that soil-structure interaction (ssi) is a crucial phenomena influencing seismic response of massive structures. cable-stayed bridge’s popularity and numbers are increasing now-a-days because of economical longer span & aesthetic good look. the current paper examines the effect of depth of foundation on seismic response of cable-stayed bridg...

displacement coefficient method (dcm) stipulated in the asce 41-06 standard is becoming the preferred method for seismic rehabilitation of buildings in many high-seismic-hazard countries. applications of the method for non-building constructions such as bridges are beyond the scope of this standard. thus its application to this kind of structure should be approached with care. target displaceme...

progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. the current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. this method is suitable especially in the case of blast-induced progressive ...

Dynamic compaction (DC) is a widely used soil improvement method in dry and/or saturated soils. The design of DC treatment is usually carried out based on the past experiences and empirical relations. In order to clarify the ambiguities in DC processes, numerical modeling of DC in dry granular soils has been considered using a dynamic finite element code. Using the developed model, two design c...

The incremental dynamic analysis is a powerful tool for evaluating the seismic vulnerability and risk of buildings. It allows calculating the global damage of structures for different PGAs and representing this result by means of damage curves. Such curves are used by many methods to obtain seismic risk scenarios at urban level. Even if the use of this method in a probabilistic environment requ...

in this paper, three dimensional (3d) static and dynamic analysis of thick plates based on the meshless local petrov-galerkin (mlpg) is presented. using the kinematics of a three-dimensional continuum, the local weak form of the equilibrium equations is derived. a weak formulation for the set of governing equations is transformed into local integral equations on local sub-domains by using a uni...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...
