First in this paper, the guidelines of diagnosis for the seismic performance of traditional timber buildings are introduced which are under development in a committee of the Agency for Cultural Affairs of Japan. Next, the evaluation method of seismic performance proposed in the diagnosis is summarized. Next, as calculation examples, the lateral loaddisplacement relationships of five temple buil...

Introduction: Several experiments performed by the astronauts on the Moon (e.g., the Apollo Lunar Surface Experiments Package, ASLEP), and proposed experiments as ground-prep for the return of humans to the Moon (RPLP-2/LPRP-2) involve the use of seismic (acoustic) energy for exploration. These seismic signals can be used for a wide array of purposes, from imaging the Lunar interior to detectin...

Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...

In certain parts of the USA, both earthquake and snow hazards may be significant. Turkstra’s rule is commonly used for load combinations. However, the rule may not be acceptable for structures that are exposed to both snow and earthquake loads that assume a significant level. In this paper, a hazard simulation computer program (HASP) is developed and Monte Carlo Simulation is performed to inves...

The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...

Response modification factors (R-factor) are used in current seismic building codes to reduce earthquake forces associated with seismic design level to determine force levels. In recent years, many authors have shown great interest in the development of seismic structural systems and several theoretical and experimental studies have been conducted to investigate performance of dampers but littl...
