The Pushover Analysis from basics - Rahul Leslie
Pushover analysis has been in the academic-research arena for quite long. The papers published in this field usually deals mostly with proposed improvements to the approach, expecting the reader to know the basics of the topic... while the common structural design practitioner, not knowing the basics, is left out from participating in those discussions. Here I’m making an effort to bridge that gap by explaining the Pushover analysis, from basics, in its simplicity.
A write up on this topic can be found at http://rahulleslie.blogspot.in/p/blog-page.html, though does not cover the full spectrum presented in this slide show.
Seismic Analysis
This document provides an overview of different seismic analysis methods for reinforced concrete buildings according to Indian code IS 1893-2002, including linear static, nonlinear static, linear dynamic, and nonlinear dynamic analysis. It describes the basic procedures for each analysis type and provides examples of how to calculate design seismic base shear, distribute seismic forces vertically and horizontally, and determine drift and overturning effects. Case studies are presented comparing the results of static and dynamic analysis for regular and irregular multi-storey buildings modeled in SAP2000.
Influence lines (structural analysis theories)
1. Influence lines represent the variation of reaction, shear, or moment at a specific point on a structural member as a concentrated load moves along the member. They are useful for analyzing the effects of moving loads.
2. To construct an influence line, a unit load is placed at different points along the member and the reaction, shear, or moment is calculated at the point of interest using statics. The values are plotted to show the influence of the load.
3. Influence lines allow engineers to determine the maximum value of a response (reaction, shear, moment) caused by a moving load and locate where on the structure that maximum occurs.

2) Examples are provided for analyzing a T-beam and an L-beam section. This includes calculating the effective flange width, checking steel strain, minimum reinforcement requirements, and computing nominal moments.
3) Reinforcement limitations for flange beams are also outlined, covering requirements for flanges in compression and tension.
Principle of virtual work and unit load method
The document summarizes the principle of virtual work (PVW) which is a fundamental tool in analytical mechanics. It defines virtual work as the work done by a real force moving through an arbitrary virtual displacement. The PVW states that if a particle is in equilibrium, the total virtual work done by the applied forces equals zero. Examples are provided to demonstrate how PVW can be used to determine unknown internal forces and slopes by equating the virtual work of external and internal forces.
Design of two way slabs(d.d.m.)
This document discusses the design of two-way floor slab systems. It compares the behavior of one-way and two-way slabs, describing how two-way slabs carry load in two directions versus one direction for one-way slabs. Different two-way slab systems like flat plates, waffle slabs, and ribbed slabs are described. Methods for analyzing two-way slabs include direct design, equivalent frame, elastic, plastic, and nonlinear analysis. Design considerations like minimum slab thickness are discussed along with examples calculating thickness.

Constructability In Construction
- Constructability refers to how well a design can be built according to specifications, on time, and within budget. Ensuring constructability involves early contractor involvement in design, design quality reviews, and consideration of construction methods and materials.
- Effective methods for identifying and preventing constructability problems include assigning a "constructability champion," using BIM with clash detection, collecting lessons learned, and conducting design reviews with contractors. Early contractor involvement in design-build projects also helps address constructability.
- Field experience is important for designers to understand construction realities. Regular site visits and communication between designers and contractors can help address issues early. Formal constructability reviews at 30%, 60%, and 90% design stages with contractor input can further

Design and Analysis of a Rocker Arm
Rocker arms are part of the valve-actuating mechanism. A rocker arm is designed to pivot on a pivot pin or shaft that is secured to a bracket. The bracket is mounted on the cylinder head. One end of a rocker arm is in contact with the top of the valve stem, and the other end is actuated by the camshaft. In installations where the camshaft is located below the cylinder head, the rocker arms are actuated by pushrods. The lifters have rollers which are forced by the valve springs to follow the profiles of the cams. Failure of rocker arm is a measure concern as it is one of the important components of push rod IC engines.Present work finds the various stresses under extreme load condition. For this we are modeling the arm using design software and the stressed regions are found out usingAnsys software. Here in this thesis we are observing that by changing different materials how the stresses are varying in the rocker arm under extreme load condition. And after comparing results we are proposing best suitable material for the rocker arm under extreme load conditions.

Design of Tank Simulator for Side-Mount Support Structure for a Spacecraft
This document describes the design of a tank simulator for a side-mounted support structure for an Indian communications satellite (GSAT). The traditional design of mounting fuel tanks inside the central cylinder increases the satellite's length-to-diameter ratio and reduces stability. The new design moves the fuel tank to the sides of the satellite, connected via a side-mount structure. This includes a central ring, top/bottom plates, ribs, flex plates, struts, and brackets. Finite element analysis was conducted applying 8g loads horizontally and 18g vertically to simulate launch stresses. Stress and displacement results for all components were within allowable limits, validating the new tank simulator design.

The document discusses the structural analysis of a rear dead axle using finite element analysis (FEA). It presents the background of the project, which involves analyzing the stresses, displacements, and frequencies on a rear axle model under working loads using ANSYS. The analysis will be conducted on models of the rear axle constructed from ductile cast iron and high-grade steel to determine which material would be more suitable. The results of the FEA, including stresses, deformations, and natural frequencies, will help evaluate the two materials.
IRJET- Seismic Analysis of Curve Cable-Stayed Bridge
1) The document analyzes the seismic performance of cable-stayed bridges with different horizontal curvatures, ranging from straight to 5 degrees of curvature.
2) Six bridge models were analyzed using the software SAP2000, including a straight bridge and bridges with 1, 2, 3, 4, and 5 degrees of curvature.
3) The results show that base shear, pier displacement, and deck displacement all decreased as curvature increased from straight to 3 degrees, but then increased again from 3 to 5 degrees of curvature. The bridges with intermediate (2-3 degree) curvature demonstrated the best seismic performance.

Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted.

Pushover Analysis of Balance Cantilever Bridge
This document discusses pushover analysis that was performed on a 3D model of a balanced cantilever bridge in CSI Bridge software. Pushover analysis applies monotonically increasing lateral loads to identify the bridge's performance under seismic loads. The analysis results, such as generation of plastic hinges, base shear, and displacement curves, are studied. The bridge is also analyzed for tracked and vehicle loads as per Indian standards. The process of modeling the bridge and defining analysis parameters in CSI Bridge software is described.
Design of short sstt confined circular hsc columns
Abstract Steel-straps tensioning technique (SSTT) has been proven to be an effective mean to confined High-strength concrete (HSC). The pre-tensioned force offers by this confining method can significantly restraint the small lateral dilation of HSC. However, most of the design guidelines only concerned with FRP-confined columns subjected to concentric compression. The direct application of these design guidelines on the SSTT-confined HSC column is being questioned due to different material and confining method adopted. Hence, a numerical study was carried out in the view of developing a simple design equation for HSC column confined with SSTT. The parameters such as SSTT-confinement ratio, load eccentricities and slenderness ratio were tested. Based on the numerical results, design equations based on regression analysis were proposed to determine the ultimate load and bending moment of SSTT-confined HSC columns. Index Terms:Confinement, Steel Straps, Eccentric loads, and Theoretical Model.
A study on plastic hinge formation in rc frame by nonlinear static analysis
This document presents a study on plastic hinge formation in reinforced concrete (RC) frames under nonlinear static pushover analysis. A single-bay, single-story RC frame is modeled and analyzed using SAP2000 software. The order and location of plastic hinge formation is observed as the frame is subjected to incremental lateral loading. Four plastic hinges form in total. The sequence of hinge formation is found to control the deformation behavior of the frame. Understanding hinge formation and the gap between successive hinges forming provides better insight into the performance of the structure under earthquake ground motions.

Non-Linear Static Analysis of Reinforced Concrete Bridge
This document discusses performing non-linear static (pushover) analysis on reinforced concrete bridges to evaluate their seismic performance. Two series of bridge models are analyzed: one with a fixed span and varying pier heights, and one with fixed pier heights and varying spans. The bridges are modeled in software and pushover analysis is conducted according to methods in FEMA 356, ATC40, and FEMA 440. The results show that the bridges designed according to Indian codes may not meet performance goals in non-linear pushover analysis. Accurately modeling material properties and structural elements is important for the non-linear analysis.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
