Hip Roof Structural Engineering

The hips are more likely than not supported by a structural member truss collar tie beam whatever at the intersection of the two hips or very close to it.

Hip roof structural engineering.

A hip roof may have the appearance of a pyramid. The shorter common rafters which may be subject to significant bending stress act to transmit load to the hip rafters. The greater the slope of the roof diaphragm the greater the contribution tro supporting the hip some. However where any discrepancies occur between these calculations and the working drawings the engineer shall be notified immediately so proper action may be taken.

These calculations shall govern the structural portion of the working drawings. In structural design a cantilever is a whole different animal and should not be confused with overhanging structural members. 10 ft 90 r1. I have a hip roof rancher with basically one long load bearing wall down the middle.

In a classic four square hip roof four hip beams convey loads from the roof peak to the corners of the exterior walls. The structural calculations included here are for the analysis and design of primary structural system. Loads can be accurately placed on the structural member.

We will need to build the beam in the attic in order to fit it into the opening. Is there anything else the structural engineer should be aware of. Overhangs are often referred to as cantilevers by the building trade.
