The distribution of stiffness, strength, and mass in both vertical horizontal orientations affects how well a high rise structure performs during powerful earthquake events. A building is considered irregular if there difference between the adjoining storeys. performance behavior regular G+10 reinforced concrete (RC) buildings under seismic loading are main topics current study. In this study, ...

Environment monitoring and automatic control of a building is a vital application of wireless sensor network; however, to maximize the network lifetime is a key challenge. The investigation of designing an efficient sensor network that minimizes energy dissipation in a battery of the sensor node, with limited battery power, is a vital consideration for the sensor network lifetime. Battery lifet...

In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...

Ice has been a serious obstacle and problem for the construction of hydraulic and marine structures, lighthouses, and the like in cold regions. For these structures, ice forces are the major design criteria. Because the ice loads caused by sea ice on offshore structures have been fully reviewed a few times, they are purposely set aside in this paper. Instead, two major problems are discussed he...

Global warming is big issue of this time. It is caused by producing emissions, mainly carbon dioxide. Many organizations tries to establish restrictions to limit CO2 emissions. Our aim is to monitor underground parking lots and detect level of carbon dioxide using wireless sensor network. Gained results are drawn in the map of pollution of monitored area.

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

Abstract Earthquake is one of the horrible natural disasters. With considerable developments in constructional science, experts have been able to find out factor forces that cause earthquakes damage and destructions different types buildings, including residential commercial caused by earthquake are high importance need be considered. The multi-story buildings usually weak points building, whic...

Tuned mass damper (TMD) have been studied and installed in structures extensively to protect the structures against lateral loads. Multiple tuned mass dampers (MTMDs) which include a number of TMDs with different parameters have been proposed for improving the performance of single TMDs. When the structural system is considered as multiple degrees of freedom (MDOF) and implemented with MTMDs, t...
