Structural Design Of Rcc Sloped Roof Pdf

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.

Structural design of rcc sloped roof pdf. The primary aim of the work is to analyze and design the pyramidal roof slab. 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. Pdf chapter 2 structural design of rcc building. This structural design process has been carried out under use of bs8110 design code of practice.

It is simple in design economical to construct and can be used on any type of structure. 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. Especially computations have been made by use of bs 8110 based spreadsheets.

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. If the problem is statically determinate the equilibrium equations would. Seismic effects material behaviour and general principles of earthquake resistant design of structures. It is the strongest type of roof because it is braced by four hip rafters.

Based on the boundary condition you can determine the axial thrust and the bending moment. A gable roof has a ridge at the center and slopes in two directions. Along the slope ii across the slope depending upon the boundary conditions. Sloping slabs under gravity load would be subjected to bending and axial thrust.

For this reason various simplified methods have been adopted for determining moments shears and reactions of such slabs. Hip the hip roof has four sloping sides.
