Building structures are analyzed in a single step using linear static analysis on the assumption that the structures are subjected to full load once the whole structure is constructed completely. In reality the dead load due to the each structural components and finishing items are imposed in separate stages as the structures are constructed story by story for nonlinear behavior of materials. Advancement of finite element modeling accelerates the accuracy of finite element simulation by taking the consideration of construction sequential effects. In this paper, rigid frame structures of both concrete and steel model of different configurations have been taken for sequential analysis. The analysis outcomes will help to understand how the structural response against loads varies for construction sequential analysis and linear static analysis while highlighting the material property. For vivid understanding of necessity of sequential analysis, analysis outcomes are eventually compared with conventional one step analysis. The effect of sequence of construction due to the self-weight of members has been studied and its effect on the overall design forces has also been highlighted using finite element modeling.

Abstract—This paper evaluates deflection of the steel high rise structure due to the P-Delta effect considering the global slenderness of the whole structure. For easy and quick design only Linear Static analysis is performed and secondary loading effect is neglected in several underdeveloped and developing countries of South Asia. Using STAADPro v8i, 40 different model is simulated to observe the severity of the P-Delta phenomenon against standard Linear Static method. 4 different storey were combined with 5 varying span in both direction for varying the slenderness of the structure. During analysis lateral load imposed with UBC94 to perform the seismic events in two directions in the seismic moderate risk zone of Bangladesh using Bangladesh National Building Code (BNBC) corresponding coefficients however wind load is omitted to observe the seismic event effect in Steel high-rise structure solely assuming outcome decision would be same if the simulation would done for wind load also. This analysis reveals how crucial side of the structure generates different deflections with changing slenderness. Test results were evaluated by storey deflection (in mm) and percentage of variation of deflection was performed by comparing P-Delta outputs with Linear Static Method outputs.

Construction works in London particularly are progressing on a scale not seen for many years for clients like Crossrail and London Underground, and for commercial and residential property developments such as Bloomberg Place, New Street Square, BBC TV Centre and Battersea Power Station. A common factor in the majority of these projects is the advanced demolition, deconstruction or dismantling of existing structures to make way for the new works. In this lecture Paul Bland, McGee Director and Nick Taylor, Head of Demolition, gave an overview of this discipline and discussed areas such as the considerations needed when planning such work, design aspects of new structures that can assist in later deconstruction, modern techniques that improve safety and reduce risk, and the logistical challenges involved. The meeting – organised by the Essex Branch of the Institution of Civil Engineers and held jointly with the Institution of Structural Engineers – drew a crowd of nearly 50 attendees to the Lord Ashcroft Building at Anglia Ruskin University in Chelmsford on Thursday 15th January 2015.

Demolition, Deconstruction & Dismantling

Abstract: Metropolitan cities are under severe threat because of inappropriate design and construction of structures. Faulty building designed without considering seismic consideration could be vulnerable to damage even under low levels of ground shaking from distant earthquake. So, structural engineers often are more concerned about the constructing Shear wall without knowing its performance with respect to infill percentage which may lead it to an over design state without knowing the demand. Nonlinear inelastic pushover analysis provides a better view about the behavior of the structures during seismic events. This study investigates as well as compares the performances of bare, different infill percentage level and two types of Shear wall consisting building structures and suggests from which level of performance shear wall should be preferred over the infill structure. To perform the finite element simulation ETABS 9.7.2 is used to get the output using pushover analysis. For different loading conditions, the performances of structures are evaluated with the help of base shear, deflection, storey drift, storey drift ratio and stages of number of hinges form and represented with discussion.

This publication provides a concise compilation of selected rules in the Eurocode 8 Part 1 & 3, together with relevant Cyprus National Annex, that relate to the seismic design of common forms of concrete building structure in the South Europe. Rules from EN 1998-3 for global analysis, type of analysis and verification checks are presented. Detail design check rules for concrete beam, column and shear wall, from EN 1998-3 are also presented. This guide covers the assessment of orthodox members in concrete frames. It does not cover design rules for steel frames. Certain practical limitations are given to the scope. Due to time constraints and knowledge, I may not be able to address the whole issues. Please send me your suggestions for improvement. Anyone interested to share his/her knowledge or willing to contribute either totally a new section about Eurocode 8-3 or within this section is encouraged.
