Week 3 Challenge

AIM:DETERMINE IRS LOADS ON 25M SPAN BRIDGE USING STAAD PRO

Introduuction:IN THE CURRENT PROJECT WE ARE APPLY METRO RAIL LIVE LOAD ON STRUCTURE WHICH SHOWN IN THE FOLLOWING FIGURE

 

 Procedure:LETS START MODELLING USING STADD PRO

STEP 1

FOR CREATING BEAM FIRST USED SNAP NODE/BEAM WHERE WE SET X AND Z GRID POINT

STEP 2

AFTER COMPLETING MODELLING AS PER PLAN WHICH SHOWN IN FIGURE

STEP 3

ASSIGN PROPERTY TO MAIN BEAM WHICH SHOWN IN FIGURE

ASSIGN PROPERTY OF CROSS BEAM WHICH SHOWN IN FIGURE

STEP 4

AFETR ASSIGNING THE PROPERTY OF BEAM ASSIGN PROPERTY OF SLAB USING 4 NODE PLATE TOOL WHICH SHOWN IN THE FIGURE

STEP 5

SELECT END NODE FOR ASSIGNNING SUPPORT WHICH SHOWN IN FIGURE

STEP 6

AFTER ASSIGNNING THE SUPPORT LETS DEFINE VEHICLE LOADS  WHICH SHOWN IN FIGURE  

AFTER DEFINNING VEHICLE LOAD THE WE DEFINE LOAD COBINATION 

WHERE X =4.33 STARTING CO ORDINATE OF VEHICLE FROM ITS START AND MOVE TOWARDS IN Z DIRECTION .FOR DEFINNING THE RANGE OF VEHICLE IN Z DIRECTION WE TAKE Z= 25 M WHICH IS THE SPAN FOR BRIDGE .AFTER DEFINNING THE LOAD COMBINATION ANALYSIS THE MODEL 

AFTER ANALYSISING  THE STRUCTURE  WE POST PROCESING IT

RESULT

WE GET MAXIMUM BENDING AT BRIDGE FROM 25 LOAD COMBINATION AND ALSO GET OTHER DETAIL WHICH PRESENT IN THE ANALYSIS FILE WHHICH IS ALREADY ENCLOSED
