Week 9 Challenge
Given data:
Roof slope 1:10
Bay spacing = 5 m
Live load = 75 kg/m^2 = 0.735 kn/m^2=0.735 x 5 =3.675 kN/m
Dead load = 5kg/m^2 + 25 kg/m ^2=30kg/m^2=0.294kN/m^2=0.294 x 5 =1.47 kN/m
AIM:
To design a 3 hinged pitched roof frame of a steel building and draw bending moment ,shear force and axial force diagrams of the frame.
Procedure:
step 1:
open staadpro software and create a new model as shown below
using nodes and beams option draw the frame as shown below.
step 2:
Define section properties in the properties Tab.
now create and assign the pinned support
step 3:
Add Dead load ,live load and load combination to the members.
output shows 0 Error and 1 warning
Result:
The given frame was analysed and the bending moment ,shear force and axial force diagram created.
bending moment diagram
shear force diagram
axial force diagram

AIM:
to draw Bending moment diagram for the frame given using staad pro
procedure:
step 1:
draw the frame using nodes and beams option
step 2:
Define and Assign the section.
step 3:
Then create and design the support to the frames
step 4:
Add load cases given and assign to frame members.
STEP 5 :
go to analysis tab ,define perform Analysis
Then click Run Analysis
output shows 0 error and 0 warnings
result:
Bending moment diagram was drawn for given frame successfully.

3deflection of frame present result staadpro
figure 1
the lateral deflection A=0.090 mm
vertical deflection at mid section of beam b& c =27.846 mm
figure 2
the lateral deflection A=1003 mm
vertical deflection at mid section of beam a& b =1005 mm
figure 3
the lateral deflection A=0.051 mm
vertical deflection at mid section of beam b =0 mm
