The building official is required to approve a design that complies with the adopted regulations. If the design does not comply with the approved regulations the building official is required to withold approval. The building official is not allowed to withold approval because the design does not comply with some requirement not formally adopted by the jurisdiction. Thus deflection criteria cannot be the basis for witholding approval.
Please clarify why basing the design on a 8 foot segment is a problem. While the total load in a 24 foot long guard rail will have a greater overall force to resist, because of the regular spacing of vertical elements calculations can typically be based on a shorter segment.
