MODELING OF MULTI-COLUMN
MODELING OF MULTI-COLUMN
Research BackgroundConstruction industries in Malaysia (buildings and bridges) are progressing in a fast pace mode. Most of Malaysias bridges built in previous 30 years, does not count seismic loading in the design calculation.
Modeling of Multi-Column Pier of Unskewed Bridge Using STAAD.Pro Under Static and Dynamic Load
Modelling and analysing multi-column pier bridge under static and dynamic load using STAAD.Pro is proposedChompreda, P. (2007).
Generate new idea and safety precautions. Produce mitigation plan and financial readiness. A stepping stone to widely practice the seismic loading into bridge design.

Objectives
Modeling of Multi-Column Pier of Unskewed Bridge Using STAAD.Pro Under Static and Dynamic Load
Research ObjectivesModelling and analysing multi-column pier bridge under static and dynamic load using STAAD.Pro is proposed To perform static and dynamic analysis of the multi-column pier of unskewed bridge using STAAD.Pro software.
To interpret and compare both static and dynamic results of multi-column pier of unskewed bridge.

Introduction
Problem StatementBridge design using BS5400 and BD37/01 no provision for seismic loading and design specification. Bridge structural integrity and stability might be affected by frequent vibrations.
Modeling of Multi-Column Pier of Unskewed Bridge Using STAAD.Pro Under Static and Dynamic Load
According to EC8, LifeSafety Requirement (ULS and DLS) for bridges in
Malaysia are not satisfied
Modelling and analysing using STAAD.Pro for concrete bridge were rarely found.
Comparison of results made between static and dynamic analysis.

Introduction
Bridge OverviewBridge can be made by concrete, steel or timber
Modeling of Multi-Column Pier of Unskewed Bridge Using STAAD.Pro Under Static and Dynamic Load
Bridge in various types is designed to serve varies purposes, geographic condition, span and types of transportation, while aesthetic value is maintained.
It could be designed as single column or multi-column per pier.
Unskewed bridge refers to the direction of bridge that perpendicular to the direction of the underneath pathway. Skewed bridge demonstrate the plan diagonal angle between bridge direction to the underneath pathway.

Literature Review
Previous Research
Modeling of Multi-Column Pier of Unskewed Bridge Using STAAD.Pro Under Static and Dynamic Load
Modelling 2D and 3D of Sultan Azlan Shah Bridge in Perak under FVA, THA and RSA for bridge pier and deck. Bridge deck and pier either in 2D or 3D, shows less than the capacity under Time History Analysis
In 3D Response Spectrum Analysis (RSA), bridge pier bending is bigger than the capacity. The bridge was tested until it cracks at 0.25g and collapse at 0.32g
