Zemin-yapı etkileşimi (ZYE) binanın periyodunu uzatırken yapısal sönüm oranını artırır. Binanın dinamik özelliklerindeki söz konusu değişim genellikle davranış açısından elverişli kabul edildiğinden ZYE tasarım yönetmeliklerinin birçoğunda ihmal edilmektedir. Fakat çok sayıda araştırma ZYE’nin edilmesinin dönme sünekliği talebinin ve tepe deplasmanının olduğundan az hesaplanması yoluyla güvensi...

Tuned mass dampers (TMDs) are widely implemented in many types of structures, such as tall buildings, wind turbines, towers, and bridges, to enhance the structural performance subjected seismic loading. In present study, we aim comprehensively investigate effectiveness TMD, by performing vulnerability assessment a 20-story steel building equipped with TMD considering soil-structure interaction ...

In the 2007 Niigataken Chuetsu-oki earthquake, soil settlement, considered to be a result of relative displacement between and structure, occurred alongside buildings at Kashiwazaki–Kariwa nuclear power plant. The objective this study is evaluate accurately influence nonlinear behavior soil-structure interface on response reactor building using three-dimensional finite element model. To achieve...

The existence of torsion, as well as consideration of the Soil-Structure Interaction (SSI), increase the natural periods of the structure resulting from a subsequent decrease in the seismic demand of the system. This paper summarizes the probabilistic assessment for evaluation of collapse fragility curves in concrete moment resisting structure with different mass center eccentricities. A 12-sto...

The base level is among the effective parameters in determining the seismic force on a structure, if the equivalent-static method is used for analyzing a structure. It is obvious that the base level is located on foundation in buildings in which foundation is built in a single level and there is not any interaction between the structure's walls and the soil; however, in some buildings which hav...

Using a climate version of a regional atmospheric model, we show that the seasonal evolution of weather is dependent on the initial soil moisture and landscape specification. Coupling this model to a land-surface model, the soil moisture distribution and landscape are shown to cause a significant nonlinear interaction between vegetation growth and precipitation. These results demonstrate that s...

This paper investigates the optimized parameters of Tuned Mass Dampers (TMDs) for high-rise structures considering Soil Structure Interaction (SSI) effects. Three optimization methods, namely the ant colony optimization (ACO) technique together with artificial bee colony (ABC) and shuffled complex evolution (SCE) methods are utilized for the optimization of TMD Mass, damping coefficient and spr...

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...
