Structural Design Of Rcc Sloped Roof Pdf

Sloping slabs under gravity load would be subjected to bending and axial thrust.

Structural design of rcc sloped roof pdf.

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. If the problem is statically determinate the equilibrium equations would. 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. Thanks srinivasan v structural engineer sharjah uae.

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. 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. 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.

Along the slope ii across the slope depending upon the boundary conditions. In staad there is one option available to give this slopped roof loads by using py direction. 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. Especially computations have been made by use of bs 8110 based spreadsheets.

Publication produced by the reinforced concrete council rcc as part of its project spreadsheets for concrete design to bs 8110 and ec2. For this reason various simplified methods have been adopted for determining moments shears and reactions of such slabs. The primary aim of the work is to analyze and design the pyramidal roof slab. It is the form most commonly used by the navy.

Hip the hip roof has four sloping sides. A gable roof has a ridge at the center and slopes in two directions. 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.
