Seismic Vibrations

The reinforced concrete structures, not designed for seismic conditions, amid the past earthquakes have shown us the significance of assessment of the seismic limit state of the current structures. During seismic vibrations, every structure encountered seismic loads. Seismic vibrations in high rise building structure subjects horizontal and torsional deflections which consequently develop extensive reactions in the buildings. Subsequently, horizontal stiffness can produce firmness in the high rise structures and it resists all the horizontal and torsional movements of the building. Therefore, bracing and shear wall are the mainstream strategies for reinforcing the structures against their poor seismic behaviours. It is seen before that shear wall gives higher horizontal firmness to the structure when coupled with bracing however it will be another finding that in building model, which location is most suitable for shear wall and bracing to get better horizontal stability. In this study, a 15 story residential reinforced concrete building is assessed and analyzed using building code ACI 318-14 for bracing and shear wall placed at several different locations of the building model. The technique used for analysis is Equivalent Static Method by utilizing a design tool, finite element software named ETABS. The significant parameters examined are lateral displacement, base shear, story drift, and overturning moment.

Seismic Loss Assessment

Abstract In this paper probabilistic seismic loss assessment of RC high rise-buildings for seismic excitation typical for Southern Euro-Mediterranean zone is presented. The loss assessment methodology developed in paper is based on a comprehensive simulation approach which takes into account ground motion (GM) uncertainty, the random effects in seismic demand as well as in predicting the damage states (DSs). The methodology is implemented on three RC high-rise buildings of 20-story, 30-story and 40-story with core wall structural system designed according to Eurocode 8. The loss functions described by a cumulative lognormal probability distribution are obtained for two intensity level for a large set of simulations (non-linear time-history analyses) based on 60 GM records with wide range of magnitudes, distance to source and different site soil conditions. The losses expressed in percent of building replacement cost for RC high-rise buildings are obtained. In the estimation of losses, both structural (S) and non-structural (NS) damage for four DSs are considered. The effect of different GM characteristics (magnitude, distance to source and site soil condition) on the obtained losses are investigated. It is checked if the estimated performance of the RC high-rise buildings fulfill limit state requirements according to Eurocode 8.

As a new type of resist lateral force structure, short-pier shear wall structure has been widely used in high-rise and super-tall residential construction. However, at present, there isn’t a specifically targeted short-leg walls structure design and construction technical regulations both at home and abroad, which led to the architectural engineering design and construction market turmoil. By the prophase research of the short-leg walls structure seismic performance, and a great deal of experiments, combine with the latest research results at home and abroad, adopt the limit state design method based on probability theory, the paper clarifies the definition of short-leg walls, and analyzes the calculation method of section load-carrying capacity for earthquake combination and no-earthquake combination, which has certain directive significance and engineering application for the design and construction of high-rise residential buildings.

Limit State Criteria

Reeling has been an attractive offshore installation method for rigid flowlines and steel catenary risers due to its fast speed, cost effectiveness and reliability. Over years of evolution, it has become a proven technology, and the understanding to the engineering fundamentals is greatly improved as well. Due to the reeling process, the pipeline is plastically deformed; residual stresses, pipe ovality, and pipe out of straightness are increased. The strength, fatigue, and fracture performance of the pipe and the girth weld have to be closely evaluated to insure the pipeline integrity during and after the installation. As part of the installation design, different types of analyses are generally carried out to demonstrate the reelability, and the pipeline responses against all limit states. However, the methods adopted by different contractors can vary greatly. In this paper, the engineering fundamentals of reeling process are reviewed. A few typical reeling analyses, both analytical and finite element based, are demonstrated with examples. The local buckling limit state criteria based on DNV-OS-F101 for different stages of reeling are also illustrated.

The vertical growth of multi storied buildings has become requisite considering limitations on housing area and upsurge in population growth. Cities with population density >10000 person/Km2may go for high rise buildings. Multiple cases of foundation failure have been observed around the globe due to incompetent soil, weak foundation, poor building materials, faulty workmanship, excess superimposed loading, want of geotechnical investigations, and failure analysis. The analysis and design of multistoried buildings [minimum G +3]is of demand in urban and economically sound areas. The STAAD. Pro is an efficient tool adhering to IS specifications for design of structures by limit state design to avoid erroneous computations, cumbersome and time consuming processes of manual calculation in India. The software is user interface to visualize, analyze and design structures by radical finite element technique and has dynamic analysis abilities. The present work is a 3-D RCC frame having 4 bays x5m along x-direction and 3 bays x5m in z- direction were taken where each floor has 299 beams and 40umns at different elevations in each floor subjected to dead, live , wind and seismic loads as per Indian beneath different load arrangements, considering structural safety under minimum requirements. The perception levels against vibrations and different foundations against failure (especially pile foundation) is stressed for a safe, comfortable multi storied building in Indian soil.
