An approach to compute optimum seismic design parameters is presented. It is based on the optimization of the expected present value of the total cost, which includes the initial cost of structures as well as the cost due to earthquakes. Different types of seismicity models are considered, including one for characteristic earthquakes. Uncertainties are included in some variables to observe the ...

The graduation started from the seismic studio of architecture engineering and designing a earthquake proof architecture. The context of the design in located in the historical garden of Uithuizen in Groningen, which is a potential seismic area. The research is based on the three different areas in seismic principles, biomimetic structure and climate. The final design is based on responding to ...

The investigation of damage to buildings in terms of non-structural walls collapse in the past earthquakes have caused researchers to study the seismic behavior of walls more extensively. Furthermore, seismic design codes have considered using wall posts to prevent wall damage, however, not many studies were done on seismic behavior change in structures due to the addition of wall posts. Theref...

Nowadays, many buildings with steel Moment Resisting Frames (MRF) are built in seismic zones when seismic codes are at its early stages of development, and as such, these structures are often designed solely to resist lateral wind loads without providing an overall ductile mechanism. On the other hand, current seismic design criteria based on hierarchy of resistance allow enhancing the structur...

Consistent with capacity design principles and requirements of ductile behavior, the 2005 AISC and 2001 CSA seismic design codes require that the intermediate horizontal boundary elements HBEs of steel plate shear walls SPSWs be designed to remain essentially elastic with the exception of plastic hinges at their ends when the infill plates fully yield under seismic loading. However, the unexpec...

The application of Heuristic Search Methods for the earthquake resistant design of structural frames is discussed. The Tabu Search method was selected for application to structural weight optimization of steel moment frame structures. A computer program was developed that uses Tabu Search for weight minimization of two-dimensional framed structures. Written in the FORTRAN computer language, the...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

Recently, there is a growing interest in seismic qualification of ridges, buildings and mechanical equipment worldwide due to increase of accidents caused by earthquake. Severe earthquake can bring serious problems in the wind turbines and eventually lead to an interruption to their electric power supply. To overcome and prevent these undesirable problems, structural design optimization of a sm...

In earthquake resistance design of structures, two general concepts have been used. The first is to increase the capacity of the structures to resist the earthquake load effects (mostly horizontal forces) or to increase the dynamic stiffness such as the seismic energy dissipation ability by adding damping systems (both devices and/or structural fuses). The second concept includes seismic isolat...
