pressures due to hurricane winds; and d) it is sometimes necessary to install a flexible joint between the block wall and the steel column where the walls have not been used to provide lateral stability; in this event the steel frame must be adequately braced to accommodate the lateral loads without collapse. 6.3.3 Metal Cladding Where metal cladding is used, Z-purlins shall be attached to the columns with suitable fixing. The vertical siding (as the vertical sheeting is called) shall be attached to the Z-purlins in the normal manner employed for roofs. Care must be taken to prevent leaks. NOTE Fixings made in the valleys rather than on the crowns would provide greater hurricane resistance.

PCTTS 599: 20XX 119 7 Floor systems 7.1 Concrete floor slabs 7.1.1 General 7.1.1.1 Single storey buildings generally utilize slabs on grade, and two-storey buildings incorporate suspended slabs on the upper floor. However, where a single storey structure is constructed on a sloping site, a suspended slab may be required. 7.1.1.2 For both categories of slabs, the finished surface of the floor shall be located no less than 300 mm above the finished ground level. On a sloping site, the floor shall be at least 300 m above the ground at the nearest point relative to the floor. NOTE This serves as a protection against flooding. 7.1.1.3 The finished slab shall be floated immediately after pouring as this produces a durable surface. Alternatively, a sand and cement screed not less than 20 mm thick may be applied to the roughened surface of the concrete. The surface shall be cleaned and washed before applying the screed. A screed of proportions of 1 part cement to 4 parts sand (by volume) is acceptable.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
