wind load - 09/26/00 06:10 AM
Dear Sir,
Software used : PV Elite V. 4.0
In calc. Of a tall silo under wind design code of UBC , the combined load stress report shows stress Ratio >> 1.0 near to 11.0 for load case of IP+WF+CW , whereas for the other load cases the ratio
is < 1.0 and okay. An investigation results in the stress due to load WF ( wind moment ( filled ) ( no CA ) goes with Beta 3 as defined in the program HELP ) is the key point . Also UBC code donot consider “ Beta 3 “ .
You are kindly requested to instruct how to cope the problem .
