NON COMPOSITE STEEL BEAM WITH WEB OPENING

To find out whether one can place an opening in the web of a steel beam, use ncbwo.exe in conjunction with EXTDAISC.doc and brun45.exe. The "brun45.exe" file is necessary because "ncbwo.exe" is not a stand- alone executable file.

The "EXTDAISC.doc" file allows you to access the required beam properties by using their standard (AISC) W designations. YOU MUST USE IT.

The AISC Load & Resistance Factor Design is used.

  • Opening can be rectangular or circular and can be eccentric to beam mid-depth.
  • Factored moment and shear at location of opening must be input.
  • Reinforcement around opening (if required) is computed.
  • Other structural details are determined.
