Executive Summary
This project details all the procedure to evaluate static and dynamic responses of a pedestrian bridge. To this end, we need to: Prepare sketches showing the layout of the structure including its member sizes and dimensions. Determine and calculate the design actions, load on the structure. Prepare for the structural analysis by establishing the appropriate combinations of actions for ultimate and serviceability limit states in accordance with the Bridge Design Code. Investigate the vibration characteristics of the bridge; perform Natural Frequency Analysis using Strand7. Develop the analysis model using Strand7 Prepare three separate load cases for Dead Loads, Pedestrian Load, and Wind load. Provide design check of stresses in several most stressed elements in tension and compression.
1. Introduction
As part of the inner City residential development, your client wishes to build a pedestrian bridge across a street with heavy traffic to connect two parts of the residential complex. The bridge should have both the staircase and lift access for pedestrians. This client has asked The Faculty of Engineering to evaluate static and dynamic responses of the proposed pedestrian bridge as a part of the review process. The engineering drawings of the pedestrian bridge and some photographs have been provided.
2. Objectives
The aim of this report is to determine if the currents components are enough to support this structure. Due to inadequate information, some assumptions and notes are given: Students will be primarily concerned with modelling a footbridge with a steel lift frame and the concrete lift pit using Strand7 finite element software. The floor of the bridge is
