Ahmad Siddiqi | Concrete Structures By Zahid

Dr. Zahid Ahmad Siddiqi holds a PhD from the University of Oklahoma, USA. With over , he has authored several other notable texts, including "Steel Structures" and "Mechanics of Materials". He has also been actively involved in the field design of numerous sizeable concrete structures and government inspection teams.

The following table outlines the major structural elements and concepts detailed in Siddiqi's work: Key Topics Covered

Covers repair/rehabilitation of structures and formwork design. Educational and Professional Value For Students

| Element | Function | Critical Design Factor | | :--- | :--- | :--- | | | Transfers loads horizontally to columns | Flexure (bending) and shear | | Columns | Carries axial compression + bending | Slenderness ratio & buckling | | Slabs | Provides floor/roof surface | Two-way or one-way action, punching shear | | Footings | Spreads column load to soil | Bearing pressure & bending moment | | Shear Walls | Resists lateral forces (wind/earthquake) | In-plane shear & overturning |

Used beneath footings or for leveling courses. It has high compressive strength but negligible tensile capacity.
