Hyperstatic Reaction Method (HRM) is a simple but effective method with attractive features in calculating internal forces and deformations of the tunnel lining. The superior ability HRM under static conditions inspires further development this for seismic design. This paper implements an improved estimating seismic-induced lining quasi-static condition. To end, modification parameter (a) appro...

After the May 12, 2008 earthquake in Wenchuan, Sichuan, suspicion grew among Earth scientists that the Zipingpu Dam reservoir had triggered the devastating earthquake, which killed more than 80,000 Chinese citizens. Since then, some 50 to 60 articles and studies have investigated this massive seismic event and its relationship to the Zipingpu reservoir. This paper reviews the literature and con...

Copper mining produces significant amounts of associate waste, leading to the construction huge waste dumps in highly seismic zone Andes Mountains. To analyze stability these deposits, it is necessary characterize mechanical properties materials laboratory, which quite difficult due large size particles composing structures. In this study, global mine analyzed by means discrete element simulati...

Strong earthquake excitation usually induces large shear strains to earth structures resulting to the generation of low shear-strength surfaces, and subsequently, to sliding along these surfaces. The generation of permanent deformations is a phenomenon commonly examined through the well-known procedure of sliding block proposed by Newmark. Nevertheless, many types of earth structures include pr...

One of the most crucial problems in geo-engineering is the instability of unsaturated slopes, causing severe loss of life and property worldwide. In this study, five novel meta-heuristic methods are employed to optimize locating the Critical Failure Surface (CFS) and corresponding Factor of Safety (FOS). A Finite Element Method (FEM) code is incorporated to convert the strong form of the Richar...

A performance-based design procedure for realistic 3D reinforced concrete (R/C) buildings is presented, that involves the use of advanced analytical tools. Depending on the building configuration, use of two alternative tools is suggested, i.e. either time-history analysis for appropriately scaled input motions, or inelastic static (pushover) analysis, both for two different levels of earthquak...
