  • 1. Structural Analysis Lab Practical File NAME: ROLL NO.: SEM: 6th BRANCH: Civil Engineering National Institute of Technology Raipur
  • 2. 1. Object: To obtain the deflection diagram, shear force diagram and bending moment diagram of the frame given below. -6.000 kN/m 4m 20.000 kN 2m 5m Y Z X Load 1
  • 3. Steps: 1) Open staad and select fileNew. Then select plane frame and units as kN and metre and press OK. 2) Using the Snap node/beam draw the frame. 3) Select the whole frame and give member properties from commandsmember propertyprismatic. Then give it a rectangular section of depth 0.4m and width 0.2m. 4) From commandssupport specifications create a fixed and a roller support and assign to the respective points by use cursor to assign command. 5) From commandsloading create a new load definition and then create a udl of 6kN and concentrated load of 20 kN as per proper requirement of the objective. Then assign the loads to the respective beams. 6) Add perform analysis to the list of commands from the tab on the left of screen. Then analyzeRun analysis. 7) Now the deflection diagram, shear force diagram and bending moment diagram can be seen by selecting it in the results menu.

Then select plane frame and units as kN and metre and press OK. 2) Using the Snap node/beam draw the frame. 3) Select the whole frame and give member properties from commandsmember propertyprismatic. Then give it a rectangular section of depth 0.4m and width 0.4m. 4) From commandssupport specifications create a fixed support and assign to the respective points by use cursor to assign command. 5) From commandsloading create a new load definition and then under nodal load create a node displacement of 5mm and assign to the respective node. 6) Add perform analysis to the list of commands from the tab on the left of screen. Then analyzeRun analysis. 7) Now the deflection diagram, shear force diagram and bending moment diagram can be seen by selecting it in the results menu.
