Abstract — Pushover Analysis Of Building

Pushover Analysis Of Building: Civil & Structural Engineering Comprehensive Investigation Integrated Analysis: ETABS · STAAD.Pro · GIS/QGIS · ABAQUS FEA · MATLAB · IoT Sensors · ~7203 Words Chapter 1: Structural Engineering Modeling & Problem Statement This section includes a an overview of the pushover analysis procedure as well as some of the concepts involved with how STAAD.Pro implements this form of analysis.

Analytical & Numerical Modeling Methodology

It is better to start with simple analytical model. The analytical model of the building should represent all new and existing components that influence the mass, strength, stiffness, and deformability of the structure at or near performance point. Elements and components shown not to significantly influence the building assessment need not be modeled.

Finite Element Results & Code Compliance

The model should perform as expected under linear static loads and modal analysis. The control node shall be located at the center of mass at the roof of a building. It should be selected in such a way that the displacement component in the direction of lateral load monotonically increases as push load increases. Separate mathematical models representing the framing along two orthogonal axes of the building shall be developed for two-dimensional analysis. A mathematical model representing the framing along two orthogonal axes of the building shall be developed for three-dimensional analysis. Independent analysis must be done while using different methods of lateral load distribution.
