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).

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.
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.
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 …
