Batubesi Dam which is located in Sorowako region in the middle part of Sulawesi island had been designed with seismic coefficient about 0.20g. The region constitutes an active earthquake zone with the recurrence frequency and magnitude of the earthquake are relatively high. The region is located on and active fault zone due to lateral fault movement (strike-slip) of Matano fault, Palukoro fault...

This study analyzes the possible modes of seismic wave for concrete gravity dams and damage occurring in body where two dam sections are taken as a case study. Model (1) is typical section dam, while model (2) provided with specified steps at its base. The design waves included Operational Base Earthquake (OBE), Maximum Design (MDE), Credible (MCE) levels. body-foundation-reservoir water intera...

In this paper, a seismic hazard assessment (SHA) of the Shigo Kas hydropower project has been performed by deterministic and probabilistic approaches. The previously developed MATLAB-based code used for SHA, incorporating local site effects through deep soil analysis. On other hand, CRISIS 2007 diffuse areal source zones. latest updated earthquake instrumental historical catalogs have developed...

The Padma Multipurpose Bridge (PMB) is one of the biggest megaprojects Bangladesh connecting third country with capital city, Dhaka. infrastructure expected to produce considerable uplift on nation’s transport system, national and regional economy, employment, household income, ultimately, poverty reduction. From construction river management points view, it most difficult engineering innovatio...

Deterministic Seismic Hazard Analysis (DSHA) for the Bangalore, India has been carried out by considering the past earthquakes, assumed subsurface fault rupture lengths and point source synthetic ground motion model. The sources have been identified using satellite remote sensing images and seismotectonic atlas map of India and relevant field studies. Maximum Credible Earthquake (MCE) has been ...

This research presents the impact of base fixity on seismic analysis including soil-structure interaction (SSI) considering linear and nonlinear soil-foundation interface conditions. A set of inelastic time history analyses using a yielding singledegree-of-freedom structural system with different fixity conditions at the base are used. The base fixity configurations considered are: 1) fixed-bas...

Dams are very important in Ghanas economic development and environmental improvement. Although Ghana dams seismically far from the active zone, accurately analysed should be evaluated since failure could severely impact people flood environment regions economy on a large scale. This paper proposes numerical procedure for static, slope stability, dynamic analysis of Akosombo embankment dam. Nine...

National (or regional) seismic hazard maps, determined from probabilistic seismic hazard analysis, quantify the expected intensity of shaking in a region(s) over the course of one or more desired time interval(s). Building codes use these maps to define the lateral force levels for the design of new and the retrofit of existing structures. In the past, the maps depicted the shaking intensity me...

In this paper, the peak ground acceleration (PGA) over the bedrock is calculated by a probabilistic and deterministic seismic hazard assessment. An active fault map of the region is prepared. For this purpose, all active faults in a radius of 100 km from Amol city center are recognized and their seismic and rapture parameters are determined. Afterwards, for seismic hazard analysis, the seismic ...

The structural performance of base-isolated buildings during past earthquakes confirmed the suitability Lead Rubber Bearing (LRB) isolators. To assess effectiveness such isolators, 3D base-fixed and associated models a multi-story building are performed for three components recorded at each stations with closest distances to seismic fault approximately 5.54, 11.39, 17.82 km 6.7 Mw Northridge ea...
