A horizontal curve provides a transition between two tangent strips of roadway, allowing a vehicle to negotiate a turn at a gradual rate rather than a sharp cut. The design of the curve is dependent on the intended design speed for the roadway, as well as other factors including drainage and friction.

The horizontal alignment is the route of the road, defined geometrically as a series of horizontal tangents (straight roadway sections), circular curves, and spiral transitions. It shows the proposed roadway location in relation to the existing terrain and adjacent land conditions.

Wind analysis can include but is not limited to evaluating comfort, wind loading on structures, as well as pollution, and natural ventilation. Below, further explanation and real-life wind evaluations and wind simulations will be discussed. Definition. Emporis defines a low-rise as “an enclosed structure below 35 metres [115 feet] which is divided into regular floor levels“.

Depending on their function, piles are classified as bearing piles, friction piles, friction-cum-bearing piles, batter piles, guide piles, and sheet piles. Based on the composition of materials, piles are classified as timber piles, concrete piles, sand piles, or steel piles.

Bar bending schedule or schedule of bars is a tabular representation of reinforcement bar. It is generally represented for each type of R.C.C work. … Bar bending schedule generally describes the particulars of bars, shape of bending with sketches and total length and weight of the bars along with their numbers.
The components are subjected to forces, which are not static, but vary in magnitude with respect to time. The stresses induced due to such forces are called Fluctuating Stresses. The most popular model for stress–time relationship is the sine curve.

Transverse reinforcement in beams is provided mainly to resist the shear forces or forces which act in a direction perpendicular to the longitudinal direction of reinforced concrete beams. … In a reinforced concrete structure both steel and concrete take part actively in resisting the shear force.

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete’s relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.

Punching shear is a type of failure of reinforced concrete slabs subjected to high localized forces. In flat slab structures this occurs at column support points. The failure is due to shear. This type of failure is catastrophic because no visible signs are shown prior to failure.

Wind pressure is given by the equation P = 0.00256 x V2, where V is the speed of the wind in miles per hour (mph). The unit for wind pressure is pounds per square foot (psf). For example, if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf.

A reinforced concrete slab is a crucial structural element and is used to provide flat surfaces(floors and ceilings) in buildings. On the basis of reinforcement provided, beam support, and the ratio of the spans, slabs are generally classified into one-way slab and two-way slab.
