Abstract
The present AISI effective width approach for determining flexural section capacities of sections with slender webs requires an iterative approach. A simplified method, called the Reference Section Method or RSM, which eliminates the need for iteration is presented and discussed. The reference section is defined as one that is similar to the actual section except for the web height. This simplified method is based on the premise that the flexural capacity of a section with slender webs is proportional to that of a reference section with compact web. The ratio of the web height of the actual section to that of the reference section defines the constant of proportionality. To demonstrate the applicability of the RSM, parametric study is performed on channel joist/rafters (MSMA sections). The capacities of the sections predicted using the RSM are compared to the AISI predicted capacities. Although the results using RSM compares well with that using the AISI specification, refinement is still possible through experimental research.

Reference Section Method for Local Web Buckling
Saint Louis, Missouri
The present AISI effective width approach for determining flexural section capacities of sections with slender webs requires an iterative approach. A simplified method, called the Reference Section Method or RSM, which eliminates the need for iteration is presented and discussed. The reference section is defined as one that is similar to the actual section except for the web height. This simplified method is based on the premise that the flexural capacity of a section with slender webs is proportional to that of a reference section with compact web. The ratio of the web height of the actual section to that of the reference section defines the constant of proportionality. To demonstrate the applicability of the RSM, parametric study is performed on channel joist/rafters (MSMA sections). The capacities of the sections predicted using the RSM are compared to the AISI predicted capacities. Although the results using RSM compares well with that using the AISI specification, refinement is still possible through experimental research.
