Foundation Prep Work
Site Investigation Site investigations should always be done before any design work, in order to obtain geotechnical information, parameters, and data about the site. Site investigation reports usually include location…
Waffle Slabs
Waffle Slabs consist of coffers, or shaped voids, in soffits of slabs. Information to provide in scheme design: ● 2-way waffle slab ● Thickness of topping ● Depth of ribs and distance of…
Ribbed Slabs
Information to provide in scheme design: ● Statement that the design is a one way ribbed slab ● Thickness of topping on top of slab ● Depth of ribs, which are small downstand…
Wall Slabs
Information to provide in scheme design: ● Thickness of slab ● Thickness of load bearing walls that support slab ● Distance between load bearing walls ● Clear floor height Reasons to use this slab…
Beam Slabs
Information to provide in scheme design: ● Thickness of slab spanning in one direction ● Size of secondary and primary beams ● Clear floor height Reasons to use this slab type: Capabilities ● Flexible…
Flat Slabs
Information to provide in scheme design: ● Constant thickness of flat slab ● Thickness of drop panels, if required. These drop panels serve as thickened section surrounding columns to provide additional shear…
Steel: Beam Design
Steel beams are to be designed to suit the following limit states: ● Bending strength at ULS (including local buckling of flange or web, lateral torsional buckling, and plastic moment capacity) ● Lateral torsional…
Steel: Column Design
Steel structural members are designed to resist yielding, buckling, and rupture under ultimate forces. Steel columns are designed to resist direct compression where the vertical applied load is applied onto…
Steel Design
There are two stages in steel design: ● Structural member design for adequate stiffness and strength ● Connection design of bolts, plates, connections, and anchors that assist to transmit forces Frequently, it…
Reinforced Concrete – Slab Design
Types of suspended slabs that are considered (slabs which are supported by beams, columns, or walls) ● Solid slabs ○ These slabs are made out of solid concrete with reinforcement that resist tension. Slabs can…
