Transcribed Image Text:PROBLEM 5
The given interior truss is subjected to wind load (bursting condition) only. Assume that
the wind pressure is directly applied on the truss. Use only the positive value of Cp for
windward roof.
Specs/data of the structure:
Velocity = 250 kph ; Exposure = B; Mean height of the structure = 6 m; Dimension of
the Square structure = 12 m by 12 m; Spacing of each truss = 3 m. Assume the
structure is rigid and enclosed structure
