This document discusses the effects of vertical irregularities in reinforced concrete frame structures on the accuracy of nonlinear static pushover analysis. It presents the results of nonlinear static pushover analysis and nonlinear time history analysis on 15 vertically irregular frame models with varying heights and types of irregularities. The models are analyzed using the SAP2000 software. The results show that pushover analysis reasonably estimates the seismic demands of vertically irregular buildings when compared to time history analysis, and the pushover results have good correlation with selected ground motion records.
P delta effect in reinforced concrete structures of rigid jointYousuf Dinar
ABSTRACT: Popularity of High-Rise structures of rigid joint frame system are increasing day by day to accommodate growing people in metropolitan city and to construct the structures without any special structural component. However combination of rigid frame with RC structure get 30 storey as maximum storey and prone to collapse under severe displacement, axial force and moment, if the P-Delta effects does not included in analysis and design phase. Due to complexity and low knowledge of P-Delta analyses designers, engineers and architectures are prone to perform Linear Static analysis which may eventually become a cause of catastrophic collapse of the high-rise. 12 cases and 2 different analysis are performed to give a light on the P-Delta effect in RC Structures of Rigid Joint which will aware and suggest concerning person to understand, make experience and perform P-Delta analysis of the high-rise for safety using numerical modelling which may accelerate the process and reduce the complexities.
Variation of deflection of steel high rise structure due to p- delta effect c...Yousuf Dinar
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.

Abstract In recent times, many research works related to seismic resistant design of structures were done and various methods of seismic resistant design were predicted and this study explains about two major seismic design methods (i.e) Force Based Design(FBD) and Direct Displacement Based Design(DDBD) in which former is a conventional method while later one is a performance approach of design. Design and Analysis were done on two dimensional bare frames of four, eight and twelve stories based on following codes IS 456, IS 1893:2000, FEMA 356 and the two design approaches were studied. Analysis and design for this study was done using Structural Analysis Program software(SAP 2000). Both design approaches is validated using non linear time history analysis for 16 different ground motion of PGA =0.32g. Structural parameters like Drift Ratio, Ductility Demand and Base shear were compared within the frames of different stories and between design approaches. Keywords: Force Based Design (FBD), Direct Displacement Based Design (DDBD), Base Shear, Ductility, Inter storey Drift, Reinforced Concrete Frames, FEMA.
Chronological construction sequence effects on reinforced concrete and steel ...Yousuf Dinar
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.

A soft storey is one which has less resistance to earthquake forces than the other storeys;
Buildings containing soft stories are extremely vulnerable to earthquake collapses, since one floor is
flexible compared to others. Vulnerability of buildings is important in causing risk to life hence special

investigation of a RC building by considering the effect of soft storey situated in seismic Zone-V of
India, in accordance with IS 1893-2002 (part-1), is taken as an example and the various analytical
approaches (linear static and nonlinear static analysis) are performed on the building to identify the
seismic demand and also pushover analysis is performed to determine the performance levels, and
Capacity spectrum of the considered, also Storey Shear is compared for 3 models by using Finite
Element Software Package ETAB’s 9.7.4 version.
Descriptive study of pushover analysis in rcc structures of rigid jointYousuf Dinar
ABSTRACT: Structures in mega cities, are under serious threat because of faulty and unskilled design and construction of structures. Sometimes structure designers are more concerned in constructing different load resistant members without knowing its necessity and its performance in the structure. Different configuration of construction may also lead to significant variation in capacity of the same structure. Nonlinear static pushover analysis provides a better view on the performance of the structures during seismic events. This comprehensive research evaluates as well as compares the performances of bare, different infill percentage level, different configuration of soft storey and Shear wall consisting building structures with each other and later depending upon the findings, suggests from which level of performance shear wall should be preferred over the infill structure and will eventually help engineers to decide where generally the soft storey could be constructed in the structures. Above all a better of effects of pushover analysis could be summarized from the findings. Masonry walls are represented by equivalent strut according to pushover concerned codes. For different loading conditions, the performances of structures are evaluated with the help of performance point, base shear, top displacement, storey drift and stages of number of hinges form.

Performance of Flat Slab Structure Using Pushover AnalysisIOSR Journals
Performance Based Seismic Engineering is the modern approach to earthquake resistant design. It
is a limit-state based design approach extended to cover complex range of issues faced by structural engineers.
Flat slabs are becoming popular and gaining importance as they are economical as compared to beam-column
connections in conventional slab. Many existing flat slabs may not have been designed for seismic forces so it is
important to study their response under seismic conditions and to evaluate seismic retrofit schemes. In this
paper we have discussed the results obtained by performing push over analysis on flat slabs by using most
common software SAP2000. A (G+7) frame having 5 bays is considered for analysis. It is observed that the
performance point of flat slab is more as compared to conventional building.
