The Roof Of A House Consists Of A 22 Cm Thick Concrete Slab

Concrete compressive strength fc 3 ksi.

The roof of a house consists of a 22 cm thick concrete slab.

On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. Around the edge of the slab the concrete forms a beam that is perhaps 2 feet deep. Live load 40 psf figure 1. The roof of a house consists of 15 cm thick concrete slab k 2 w mk that is 15 m wide and 20 m long.

The roof of a house consists of a 22 cm thick concrete slab k 2 w m k that is 15 m wide and 20 m long. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2 c respectively. A 4 or 6 inch layer of gravel lies beneath the slab. Steel yield strength fy 40 ksi.

The rest of the slab is 4 or 6 inches thick. The roof of a house consists of a 15 cm thick concrete slab k 2 w m k that is 15 m wide and 20 m long. On a clear winter night the. Slabs s1 and s2 to be designed.

The inner surface of the roof is maintained at 15 c. On a clear winter night. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m 2 c respectively. The roof of a house consists of a 22 cm thick concrete slab k 2 w m k that is 15 m wide and 20m long the emissivity of the outer surface of the roof is 0 9 and the convection heat transfer coefficient on that surface is estimated to be 15 w m 2 k the inner surface of the roof is maintained at 15 c.

On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. The roof of a house consists of a 15 cm thick concrete slab k 2 w m k that is 15 m wide and 20 m long the convection heat transfer coefficients on the inner and outersurfaces of the roof are 5 and 12 w m 2 k respectively. 2 thick brick tile. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2k respectively.

A 4 millimeter sheet of plastic lies between the concrete and the gravel to keep moisture out. The roof of a house consists of a 15 cm thick concrete slab k 2 w m c that is 15 m wide and 20 m long. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and l w m 2 k respectively. The inner surface of the roof is maintained at 15 c.

Design the roof slab beam and column of house given in figure 1. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. On a clear winter night the ambient air is reported to be at 10ºc while the night sky temperature is 100k. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k.

The emissivity of the outer surface of the roof is 0 9 and the convection heat transfer coefficient on that surface is estimated to be 15 w m2 k.
