The significance of incorporating soil-structure interaction effect in the analysis and design of RC frame buildings is increasingly recognized but still not penetrated to the grass root level owing to various complexities involved. It is well established fact that the soil-structure interaction effect considerably influence the design of multi-storey buildings subjected to lateral seismic load...

A structural optimization criterion for linear mechanical systems subject to random vibrations is presented for supporting engineer’s design. It is based on a multiobjective approach whose Objective Function (OF) vector is done by stochastic reliability performance and structural cost indices. The first ones are structural reliabilities, and are evaluated for one or more failure types; they are...

Seismic base isolation is now a days moving towards a very efficient tool in seismic design of structure. Increasing flexibility of structure is well achieved by the insertion of these additional elements between upper structure and foundation as they absorb larger part of seismic energy. However in Bangladesh, this research is still young for building structures. Therefore, this is a burning q...

Abstract In recent years, the tuned mass damper inerter (TMDI) has been demonstrated in several theoretical studies to be an effective vibration absorber for seismic protection of non-isolated buildings. Its effectiveness relies on careful tuning TMDI stiffness and damping properties, while its performance improves with increase inertance property which is readily scalable. Nevertheless, all pr...

Added Damping and Stiffness (ADAS) steel dissipators are among the most classical devices installed in dissipative bracing systems for advanced seismic retrofit of frame buildings. An energy-based sizing procedure is formulated this study class dampers, where total number constituting plates directly related, without iterative steps, to supplementary damping energy required jointly reduce stres...

Abstract. This study presents an original inelastic beam-like model for the simulation of nonlinear dynamic behaviour three-dimensional buildings subjected to earthquake loadings. The proposed is defined as a step-wise shear only cantilever beam, whose segments have same mechanical properties corresponding inter-storeys building. inter-storey constitutive laws are calibrated by means results st...

The optimization of (organizational) learning processes (e.g. Crossan et al., 1999; Bontis et al., 2002) appears as a key motivation – albeit often implicit – for the development of Knowledge Management (KM) strategies (Balbastre et al., 2003). This learning may either involve the exploitation or the exploration of knowledge (March, 1991). Knowledge exploitation aims to prevent unnecessary dupl...

The Cuckoo search algorithm is a recent addition to metaheuristic techniques. It simulates the breeding behaviour of certain cuckoo species into a numerical optimization technique. Cuckoo birds lay their eggs in the nests of other host birds so that their chicks when hatched can be nurtured by the host birds. The optimum design algorithm presented for moment resisting steel frames is based on t...

This work presents an efficient approach using time-varying autoregressive with exogenous input (TVARX) model and a substructure technique to identify the instantaneous modal parameters of a linear timevarying structure and its substructures. The identified instantaneous natural frequencies can be used to identify earthquake damage to a building, including the specific floors that are damaged. ...

Base isolation is an increasingly applied earthquake-resistant design technique in highly seismic areas. Examination of the actual performance of isolated structures in real earthquake has become a critical issue. In this paper, a new computational method for system identification is proposed for obtaining insight into the linear and nonlinear structural properties of based-isolated buildings. ...
