Foundation design is a process of designing the footing and foundation walls of the structure. The footing can be of many varieties, for example, strip or continuous footings, drilled piles, mat foundations, etc. Designing a foundation is dependent on the geotechnical report.

Columns support floors in a structure. Slabs and beams transfer the stresses to the columns. So, it is important to design strong columns. A column is defined as a compression member, the effective length of which exceeds three times the least lateral dimension.
Web buckling occurs when intensity of vertical compressive stress near centre of section becomes greater than the critical buckling stress for the web acting as a column.

A temporary oriented base plate is used for leading the drill bit and conductor to the site of well hole on the seabed. This device is welded with steel plate and rebar, and filled with concrete in the center.
The steel sections manufactured in rolling mills and used as structural members are known as rolled structural steel sections. The steel sections are named according to their cross sectional shapes. … Such steel sections are known as regular steel sections.
Strength of the material considered under the shear failure, when a structure will fail is known as the design shear strength. The shear strength without any shear reinforcement relies on compressive concrete grade and percentage of tension steel in beam

A slab-on-grade foundation—also known as a floating slab foundation—is a structural engineering practice in which the concrete slab that will serve as the foundation for a building or other structure is formed from a mold that is set into the ground.

The effective depth of the beam is the distance from the tension steel to the edge of the compression fiber. Meaning if you have a 400 mm deep beam with T20 tension reinforcement and a cover of 40 mm the effective depth is 400 – 40 – 10 = 350.

Circular Column: Circular columns are mostly used in piling and elevation of the buildings for aesthetic purposes. In a circular column, more than 4 longitudinal steel bars are used as a reinforcement bar and its bending resistance is generally higher than the square or rectangular column.

A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings.

Solid Slabs are fully customizable concrete slabs of varying width, length and thickness. Solid Slabs can be designed and produced with mild reinforcing or by adding prestressing strands. … Solid Slabs can be cast with specialty inserts for lifting, mounting or connecting hardware.

The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Beam span maximums are based on

It may become necessary to determine the section modulus of the precast prestressed section for a composite slab of given depth and either case, formulae relating the section moduli of the precast prestressed and composite section loading on the member, permissible stresses in the concrete and loss ratio

The ultimate bearing capacity of a pile is the maximum load which it can carry without failure or excessive settlement of the ground. The bearing capacity of a pile depends primarily on 3 factors as given below, Type of soil through which pile is embedded. … Pile dimension (cross section & length of pile)

A pile cap (Figure 1) is a stocky reinforced structure which spreads and distributes the load from acolumn or bridge pier downwards into supporting piles. Unlike standard deep beams, pile caps arerelatively wide, with a width comparable to their span, contain relatively low reinforcement and inparticular normally no transverse shear reinforcement [1].Discrepancies exist in the

An end plate connection, as shown in Fig. 1, consists solely of a vertical plate shop-welded to the end of the web transverse to the axis of the beam with fillet welds on each side of the web. The field connection is made by bolting the end plate to the flange or web of the supporting

Moment connections are designed to transfer bending moments, shear forces and sometimes normal forces. The design strength and stiffness of a moment connection are defined in relation to the strength and stiffness of the connected members.

Shear is the term assigned to forces that act perpendicular to the longitudinal axis of structural elements. … Concrete beams are expected to crack in flexure, with such cracks forming perpendicular to longitudinal tension reinforcement, i.e., perpendicular also to a free edge.

In terms of design, the term ‘section’ typically refers to a view of a structure as though it has been sliced in half or cut along another imaginary plane, which is generally, but not always a vertical plane. This is represented as a ‘section drawing’ or ‘sectional drawing’.
