Designing a water tank or a reservoir requires a different mindset. While the Limit State of Collapse remains relevant, the Limit State of Serviceability becomes paramount. A crack in a water tank is a structural failure regardless of whether the tank collapses.
Shah and Karve’s book breaks this down into two primary categories:
Columns are designed for axial load or combined axial load and bending (uniaxial/biaxial). The text explains: Short columns (axial load only). Columns with bending moments. Designing a water tank or a reservoir requires
and S.R. Karve are well-respected figures in the field of structural engineering in India. Shah and Karve have co-authored several other important textbooks, including Illustrated Design of Reinforced Concrete Buildings , which covers the design of G+3 storeyed buildings along with earthquake analysis and design. Their expertise is grounded in the Indian construction context, which makes their books particularly valuable for engineering students and practicing professionals in the country.
Plane sections normal to the axis remain plane even after bending. Shah and Karve’s book breaks this down into
The Limit State Method (LSM), codified in the Indian Standard IS 456:2000, represents a shift toward reality. It acknowledges that materials yield, crack, and deform before failure.
Features specialized content on fire resistance, corrosion, and earthquake-resistant detailing. It acknowledges that materials yield
Unlike previous methods that focused solely on a constant factor of safety, Shah and Karve’s work emphasizes a —treating loads and material strengths as variables with statistical distributions. This is managed through two primary "limit states":
Different factors are applied to Dead Loads, Live Loads, and Wind/Earthquake Loads based on their predictability.
