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.

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 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.

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.

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 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.

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

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.

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.

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.

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.
