Hip Roof Structural Engineering

A hip roof may have the appearance of a pyramid.

Hip roof structural engineering. The structural calculations included here are for the analysis and design of primary structural system. I have a hip roof rancher with basically one long load bearing wall down the middle. Overhangs are often referred to as cantilevers by the building trade. These calculations shall govern the structural portion of the working drawings.

But look to the obvious for the solution here. 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. In a classic four square hip roof four hip beams convey loads from the roof peak to the corners of the exterior walls.

Loads can be accurately placed on the structural member. I want to remove a section of this wall 25 long and put a beam in the attic. Ht h base b area bxh 2 45 45 10 ft x 1 414 10 ft 14 14 ft. We will need to build the beam in the attic in order to fit it into the opening.

Hip roofs are structurally efficient because the hip rafters tend to act in compression rather than in bending. 10 ft 90 r1. 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.
