Structural Design Of Rcc Sloped Roof Pdf

In staad there is one option available to give this slopped roof loads by using py direction.

Structural design of rcc sloped roof pdf.

Based on the boundary condition you can determine the axial thrust and the bending moment. It is the strongest type of roof because it is braced by four hip rafters. A gable roof has a ridge at the center and slopes in two directions. For this reason various simplified methods have been adopted for determining moments shears and reactions of such slabs.

Along the slope ii across the slope depending upon the boundary conditions. If the problem is statically determinate the equilibrium equations would. The primary aim of the work is to analyze and design the pyramidal roof slab. Rcc slab roof design example structural concrete roof or slab is made waterproof by applying stabilised bitumen sheets the floor is first cleaned and then some bitumen is sprinkled over the surface and then bitumen stabilised sheets are rolled over the surface and joined with other at edges by applying heat through gas torch.

Roof snow drift surcharge a n g l e note a 15 increase in the allowable capacity of wood for loads that include snow which is a short term load snow loads 7 12 cs 0 99 slope 8 12 0 91 9 12 0 83 10 12 0 75 11 12 0 69 12 12 0 63 note that roofs exceeding an angle of 30 degrees may reduce the ground snow load. Sloping slabs under gravity load would be subjected to bending and axial thrust. According to the 1995 aci code all two way reinforced concrete slab systems including edge supported slabs flat slabs and flat plates are to be analyzed and. It is simple in design economical to construct and can be used on any type of structure.

Pdf chapter 2 structural design of rcc building. Hip the hip roof has four sloping sides. It is the form most commonly used by the navy. Thanks srinivasan v structural engineer sharjah uae.

Especially computations have been made by use of bs 8110 based spreadsheets. Staad is automatically resolve the forces based on slope of roof given. Model the beam slab as per your slope requirement then assign the load through py option instead of gy fy. Design loads for residential buildings 3 1 general loads are a primary consideration in any building design because they define the nature and magnitude of hazards or external forces that a building must resist to provide reasonable performance i e safety and serviceability throughout the structure s useful life.
