EXTERNAL WIND PRESSURE is the physical principle behind the pressure tube (Pitot) or pressure-plate anemometer. The wind pressure is also used to orient wind vanes and measure the wind direction.
The pressure plate measures the deflection of a flat plate that is continually oriented along the wind direction by a vane.
Dynamic wind load gives rise to vertical motion, creating oscillations in any direction. Like the breaking of an overused violin string, oscillations are vibrations that can cause a bridge to fail.
AXIAL COLUMN SHORTENING In tall buildings, columns carry huge loads which effectively compress the column along its axis. This is commonly known as ‘axial shortening’.
The axial column displacements generate significant forces within the structural elements they support, and can also cause failure of surrounding non-structural elements.
Circular Column: Circular columns are mostly used in piling and elevation of the buildings for aesthetic purposes.
In a circular column, more than 4 longitudinal steel bars are used as a reinforcement bar. Its bending resistance is generally higher than the square or rectangular column.
Rigid beam-to-column connections are generally subjected to axial and shear forces in addition to bending and torsional moments. Design equation for end-plate thickness of these connections has been extensively investigated
Friction-type connections are widely used to connect steel members where slipping is not permitted under serviceability loads. The friction developed between the faying surfaces transfers the design shear forces at the serviceability limit states. The bolts act in tension and are not subject to shear.
Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called ‘drop panels’
