Combined footings are constructed for two or more columns when they are close to each other and their foundations overlap. Design of combined footings with example is discussed. The function of a footing or a foundation is to transmit the load form the structure to the underlying soil.

The term column applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a post, and supports with a rectangular or other non-round section are usually

Four-sided concrete culverts, commonly referred to as box culverts, are some of the most versatile precast concrete products on the market. Box culverts are suitable for applications such as underpasses, tunnels, subways, bridges, stream culverts, material handling, storage, and more.
BOQ means a bill of quantity is a document prepared by a cost estimator to calculate the exact costing of project work by multiplying item work by their rate.

They provide vertical support and connection to transfer loads to the building foundation, acting as a brace for the structural loads supported by the columns. … Column base connections are arguably the most important connections in the entire building, transferring flexure, shear, and axial force from the entire structure into the foundation.

The base plate acts as an interface between the superstructure and the foundation; thus, completing the load path into the foundation. Base plates help provide a uniform distribution of superstructure loads to the foundation, and therefore conform to the shape of the foundation, typically a square or a rectangle.

Lateral loading is the continuous and repeated application of a load on an object or structural component in a horizontal direction or parallel to the x-axis. Lateral loading can cause a material to shear or bend in the direction of the force and ultimately lead to the failure of the material.

Program Description: “MOVLOADS” is a spreadsheet program written in MS-Excel for the purpose of analysis of simple-span memberssubjected to from one (1) up to eight (8) moving wheel loads with up to seven (7) wheel spacings. Specifically,the maximum moment and location from the left end of the member and wheel postioning, the maximum endshears, the

The lateral Earth pressure due to earth pressure is the major force acting on the retaining wall. Retaining walls support soil and other materials laterally. That is, retaining walls “retain” earth, keeping it from sliding. Retaining walls must resist overturning and sliding, and the pressure under the toe (front bottom edge of footing) should not exceed the

A roof beam is the primary load-bearing element in your roof. It provides support to the roof or floor above, and strengthens your walls, keeping them securely in place to prevent them from spreading out or leaning in.

A corbel is a short cantilever projecting out from a column, a wall, or the side of a beam. A corbel is designed to support another member, usually a beam or girder, but may also be used to support a slab. ACI 318 restricts the term “corbel” to a member having span-to-depth ratio which is less
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

Axial tension tends to straighten the beam, thus counteracting the bending moments produced by the transverse load. On the other hand, since axial compression may greatly increase the bending moment and the slope and deflection of the beam, it is the more serious type of axial load.
