Structural design of rcc sloped roof pdf.

Sloping slabs under gravity load would be subjected to bending and axial thrust. 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. If the problem is statically determinate the equilibrium equations would. Pdf chapter 2 structural design of rcc building.

The primary aim of the work is to analyze and design the pyramidal roof slab. It is the strongest type of roof because it is braced by four hip rafters. Hip the hip roof has four sloping sides. Especially computations have been made by use of bs 8110 based spreadsheets.

Model the beam slab as per your slope requirement then assign the load through py option instead of gy fy. Along the slope ii across the slope depending upon the boundary conditions. This structural design process has been carried out under use of bs8110 design code of practice. Based on the boundary condition you can determine the axial thrust and the bending moment.

In staad there is one option available to give this slopped roof loads by using py direction. Publication produced by the reinforced concrete council rcc as part of its project spreadsheets for concrete design to bs 8110 and ec2. It is the form most commonly used by the navy. 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.

A gable roof has a ridge at the center and slopes in two directions. 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. Staad is automatically resolve the forces based on slope of roof given. Different boundary conditions are considered like pyramidal panels a with and without ridge beam b with and without edge beam c supported on wall and d supported on columns with.
