Because of the limitations posed by topographic conditions, buildings located on hill slopes have highly irregular configurations in comparison with flat terrain. Extensive field surveys were conducted two test bed cities, Mussoorie and Nainital, situated Himalayan state Uttarakhand India, order to develop a comprehensive building stock inventory. Depending arrangement relative levels foundations, six different structural identified. A total 57 typologies identified classified using...

Summary A suite of reinforced‐concrete frame buildings located on hill sides, with 2 different structural configurations, viz step‐back and split‐foundation, are analyzed to study their floor response. Both split‐foundation configurations lead torsional effects in the direction across slope due presence shorter columns uphill side. Peak acceleration response spectra obtained at each storey's center rigidity both its stiff flexible edges. As reported previous studies as well, it is observed...

Modern seismic building design codes tend to converge on issues of methodology and the state-of-the-art. However, significant differences exist in basic provisions various codes. This paper compares important related RC buildings some major national viz. ASCE 7, Eurocode 8, NZS 1170.5, IS 1893. Code regarding specification hazard, site classification, response spectrum, ductility reduction factors, minimum base shear are compared their cumulative effect is studied. The objective component...

Summary The structural configurations of hillside buildings are significantly different than those observed on flat terrain. To study the effect often buildings, collapse fragility regular “flat land (FL)” and irregular “split‐foundation (SF)” “step‐back (SB)” is studied using incremental dynamic analysis. effects building height, seismic zone, near‐ far‐field sites investigated. It that SF SB exhibit significant torsional at storey just above uppermost foundation level. In case FL occurs...

Incremental dynamic analyses are conducted for a suite of low- and mid-rise reinforced-concrete special moment-resisting frame buildings. Buildings non-conforming conforming to the strong-column weak-beam (SCWB) design criterion considered. These buildings designed two most severe seismic zones in India (i.e., zone IV V) following provisions Indian Standards. It is observed that SCWB lead an undesirable column failure collapse mechanism. Although yielding columns cannot be avoided, even...

A range of reinforced concrete frame buildings with different levels inelasticity as well periods vibration is analyzed to study the floor response. The derived acceleration response spectra are normalized by peak ground acceleration, and spectrum. normalization respect spectrum leads lowest coefficients variation. Based on this observation previous studies, an amplification function proposed that can be used develop design from motion spectrum, considering building's dynamic characteristics...

Two analytical models for unreinforced masonry (URM) buildings are proposed with the aim to simulate their seismic response and estimate corresponding vulnerability functions. The implemented in SAP 2000 nonlinear software obtain capacity curve parameters representative Indian URM buildings, based on a field survey statistical analysis. Vulnerability functions estimated using obtained curves. Damage Probability Matrices (DPMs) approximate PGA-intensity correlation relationship as per...

In this study, the effects of implementing stochastic finite fault ground motion simulations in earthquake hazard and risk assessment are evaluated. The investigations conducted for city Dehradun (Indian Himalayas). We compare two estimation techniques: a prediction equation–based technique simulation-based technique. comparison focuses on differences techniques imply damage loss estimates.

Very few earthquake risk studies exist for cities on the Indian subcontinent. The that do typically focus intensity as parameter to describe expected ground motion during an and damage observations represent building vulnerability. In contrast these empirical studies, analytical loss computations, which are based capacity spectrum methods (CSM), have recently become popular gaining wide acceptance. Analytical computations been conducted test bed Dehradun, a city of 500,000 inhabitants in...

Predicting the consequences of large earthquakes to built environment is high importance for disaster control, civil protection and emergency planning. A number software tools are now available estimate physical building damage associated losses in terms casualties economic losses. In recent years, SELENA, a seismic risk loss assessment which makes use capacity spectrum method (CSM), has been developed into widely applicable tool. Since SELENA functions independently from Geographic...

Abstract Mit der Ingenieuranalyse Erdbebenschäden des Magnitude6.6 Bingöl‐Erdbebens (Türkei) vom 1. Mai 2003 wird Versuch unternommen, schadenbegünstigende Einflußfaktoren herauszuarbeiten. Die Schadensauswertungen, die instrumentellen Standortuntersuchungen und Reinterpretation Bauwerksverhaltens konzentrieren sich dabei auf vor Ort aufgenommenen Stahlbetonkonstruktionen. Im Mittelpunkt stehen mehrgeschossige Schulgebäude, trotz ihres Typenprojektcharakters deutliche Unterschiede im...
