In: Civil Engineering
You are required to design a watch tower. The watch tower is circular and has an outer diameter of 1500mm. The tower is built of 2 skins of masonry brick work. The supplier data sheet says that the density of the brickwork is 1900 kg/m3 . The tower has a slab at the top and watchmen sit there. The tower is built on a square concrete slab 2m by 2m. the slab is 300mm thick. It has finishes of 50mm on it. The concrete slab sits on masonry walls that are 4m high above ground level. These walls are also double skin walls. The foundation is a strip footing. The geotechnical engineer has given you an allowable bearing pressure of 300 kPa at a depth of 1000mm below ground level. The height of the watch tower from the top of the concrete slab to the top of the tower is 10m. Determine the minimum width of the foundation. Also determine the factored loads in the foundation? Use factors 1.2 DL + 1.6 LL.
