Reinforcement columns

Consider a column with cross section 300×300. This is the smallest allowable column section when seismic behavior is required. It is reinforced with 4 longitudinal bars and one stirrup. The cross section described is not generally used but it was chosen in this introductory paragraph for training purposes. The column has a length of 2.70 […]

REINFORCEMENT STEEL SPECIFICATIONS

Raft foundation

The extensive foundation (which is usually called raft foundation), is a unified foundation that extends throughout the entire area of the columns. As a rule, raft foundation is used as a building’s foundation when the soil has a low bearing ca-pacity. The behaviour of the raft foundation resembles the behaviour of a strip foundation grate. […]

Sandwich-voided slabs

In reality, sandwich-voided slabs are ribbed slabs with a slab placed both on their upper and lower surface. Sandwich slabs may have the disadvantage of a larger weight compared to the ribbed ones but on the other hand, they have the advantage that their spans and supports behave in the same proper way. Their construction […]
