Hip Roof Structural Engineering

Hip roofs are structurally efficient because the hip rafters tend to act in compression rather than in bending.

Hip roof structural engineering.

These calculations shall govern the structural portion of the working drawings. We will need to build the beam in the attic in order to fit it into the opening. 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. A hip roof may have the appearance of a pyramid.

However where any discrepancies occur between these calculations and the working drawings the engineer shall be notified immediately so proper action may be taken. In structural design a cantilever is a whole different animal and should not be confused with overhanging structural members. Ht h base b area bxh 2 45 45 10 ft x 1 414 10 ft 14 14 ft. 10 ft 90 r1.

Loads can be accurately placed on the structural member. The shorter common rafters which may be subject to significant bending stress act to transmit load to the hip rafters. But look to the obvious for the solution here. I want to remove a section of this wall 25 long and put a beam in the attic.

The greater the slope of the roof diaphragm the greater the contribution tro supporting the hip some. 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.
