## PURLIN SPACING CALCULATION ALONG WITH MEMBER

To calculate the number of boards needed for purlins, divide the length of the purlin rows by the length of boards you are using (e.g. two boards of length eight feet for each 16 foot long purlin row).

Pile behaves as a transversely loaded beam in case of lateral loads and they transfer lateral load to surrounding soil by means of lateral resistance of the soil. Pile shifts horizontally in response to applied load which results in bending, rotation or translation of pile.

## DESIGN OF PILES BASED ON LOAD CAPACITY

It is also known as the bearing capacity of piles. … Pile load capacity calculation is done for single pile or a group of piles based on the requirement of number of piles for the given load or size of foundation.

## COMBINED FOOTING DESIGN

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.

## Design Rectangular Tied Column

A tied column, shown in Figure 1, is a column in which the longitudinal reinforcement bars are tied together with separate smaller diameter transverse bars (ties) spaced at some interval along the column height. … The cross sections of such columns are usually square, rectangular, or circular in shape.

## PILECAP DESIGN to BS 8110:1997

Pile caps are constructed to hold the pile and superstructure together at the ground level or below the ground level while transferring loads of the superstructure to the foundation. … Pile caps can be designed using the truss analogy or using the bending theories.

## AXIAL LOAD / MOMENT DIAGRAMS: CIRCULAR COLUMNS

Axial loading is defined as applying a force on a structure directly along an axis of the structure. Axial moment is applied in the plane perpendicular to the beam axis. … It is defined in beam coordinate system only.

## AXIAL LOAD / MOMENT DIAGRAM to BS8110

Axial Force Diagram: It is a diagram which represents the axial force graphically with proper scale and sign. The sign and scale refers the ordinate of axial force at each point along the length of member. Axial moment is applied in the plane perpendicular to the beam axis. … It is defined in beam coordinate system only.

## Load distribution and lateral stability

Distributed scheduling is concerned with distributing the load of a system among the available resources in a manner that improves overall system performance and maximises resource utilisation. The basic idea is to transfer tasks from heavily loaded machines to idle or lightly loaded ones. lateral stability is the property of an object to develop forces or to

## COMBINED MOMENT & DEFLECTION TABLES

You cannot establish a direct relationship between deflection and moment. Deflection depends on the load, span, Modulus of elasticity and the Moment of Inertia. … The maximum moment is at the support where the deflection is zero. The maximum deflection is at the free end of the cantilever where the moment is zero.

## Combined Footing Design Based on ACI 318-02

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.

## ELECTRICAL EQUIPMENT FOUNDATION INSPECTION REPORT

The service inspection involves the observation of how well the electrical service was installed. During this phase, the main panel will be taken a closer look at to make sure it was put in place properly, and it has been grounded properly

## Design of PT Slabs on Compressible Soil Ground Based on Specification of PTI

Post tension slab is a combination of conventional slab reinforcement and additional protruding high-strength steel tendons, which are consequently subjected to tension after the concrete has set. This hybridisation helps achieve the formation of a much thinner slab with a longer span devoid of any column-free spaces.

## Program for Combined Foundation Design With Piles

The design of pile foundation involves providing adequate pile type, size, depth, and number to support the superstructure load without excessive settlement and bearing capacity failure. … The resistance to the applied structural load is derived mainly from the frictional resistance developed at the soil–pile interface.

## Plain Concrete Footing Design Based on ACI 318-02

Plain concrete footing or pedestal is a shallow foundation designed to take small loads from column without using longitudinal or main reinforcement bars. These are the most economical forms of shallow foundation.

## Pad Footing Design Based on ACI 318-02

Pad foundations are a form of spread foundation formed by rectangular, square, or sometimes circular concrete ‘pads‘ that support localised single-point loads such as structural columns, groups of columns or framed structures. This load is then spread by the pad to the bearing layer of soil or rock below.

## Design and Construction of Lifting Beams

Design and Construction of Lifting Beams,” Engineering Journal, American Institute of Steel Construction, Vol. … Lifting beams (also known as spreader beams) are used to assist in the hoisting process. Most erectors and riggers accumulate an assortment of lifting beams during the course of time.

## Design of Lifting Lug Weld

The design of a lifting lug is made up of four parts; the lug plate, the weld size used to connect it to a shell or structure, the bearing stress at the pin hole and the end area of the lug. … Their design is also based on the radius of the lug and not on

## Grade Beam Design Based on ACI 318-99

Grade Beam is a beam that is built at Grade level (earth level) mostly used to buildings with piles and to connect pile caps to each other. Grade Beams are reinforced concrete members which are constructed to act as horizontal ties between footings or pile caps.
