Abstract. The equivalent linearization program LSSRLI-1, proposed by Xiaojun Li in 1989, is the important content in seismic zoning work and seismic safety evaluation of engineering sites. It is necessary to check the applicability of LSSRLI-1 to all kinds of sites. The mainly elaboration of this paper is verifying the applicability of seismic safety evaluation program LSSRLI-1 in stiff and hal...

In recent years, the micro seismic monitoring technology have the widespread application in Chinese reservoir geological activity monitoring and mine safety monitoring. The effect of micro seismic monitoring technology is very good. However, in the study of micro earthquake, Chinese research started late relatively with foreign. This paper summarizes the current Development status and the appli...

Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

 Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...

development of new methods in seismic analysis and increasing application of performance based seismic design necessitate the study of the seismic performance of structures designed based on iranian regulations. in this study the seismic performance of steel moment-resisting frames designed based on the tenth code of the iranian national building regulations is investigated. frames are differen...

Large dams, especially concrete dams, have been designed against earthquakes since the construction of Hoover dam in the 1930s. The design criteria and methods of analysis used in those times are outdated today and the actual seismic safety of these structures is not known in view of today’s requirements. Earthquake action was usually taken into account pseudostatically, through an inertia forc...

–This paper presents the main features and organization of STAADPRO, a computer program that has been developed for the static and seismic stability evaluations of concrete gravity dams. STAADPRO is based on the gravity method using rigid body equilibrium and beam theory to perform stress analyses, compute crack lengths, and safety factors. Seismic analyses could be done using either the pseudo...

BACKGROUND Overweight and obesity are common among patients with Cushing's syndrome (CS) and may persist in some patients even after ostensibly curative surgery, contributing to cardiometabolic dysfunction and increased cardiovascular risk. Mifepristone, a selective glucocorticoid receptor antagonist, was effective in controlling hyperglycemia in a 24-week trial of adults (N = 50) with endogeno...

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 ...
