Structural Design Of Rcc Sloped Roof Pdf
Publication produced by the reinforced concrete council rcc as part of its project spreadsheets for concrete design to bs 8110 and ec2.
Structural design of rcc sloped roof pdf. It is simple in design economical to construct and can be used on any type of structure. 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. Especially computations have been made by use of bs 8110 based spreadsheets. 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.
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 strongest type of roof because it is braced by four hip rafters. If the problem is statically determinate the equilibrium equations would.
Seismic effects material behaviour and general principles of earthquake resistant design of structures. Based on the boundary condition you can determine the axial thrust and the bending moment. Ductile design and detailing of earthquake resistant structures. 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. Sloping slabs under gravity load would be subjected to bending and axial thrust. 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. It is the form most commonly used by the navy.
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.
