DUCTILITY REQUIREMENTS FOR BUILDINGS

the brittle failure as result of inelastic deformation can be avoided only if the concrete is made to behave in a ductile manner so that the member can absorb and dissipate large amount of energy. Hence in the case of reinforced concrete members subjected to inelastic deformation, not only strength but also ductility plays vital role in the design.

Moreover, during a major earthquake, in ductile structures where the diaphragms are designed to remain essentially elastic, the superstructure

Types of Retaining Walls - Structural Engineers

Retaining walls are structure used to retain soil, rock or other materials in a vertical condition. Hence they provide a lateral support to vertical slopes of soil that would otherwise collapse into a more natural shape. Most common materials used for retaining walls are:

Design Guide for Hot Dip best practice - GB Galvanizing

Design Guide for Hot Dip Galvanizing – best practice for venting and draining Purpose Formation of the hot dip galvanized coating occurs from the reaction of ferrous metal and molten zinc. The ferrous metal needs to have a clean, unoxidised surface for the molten zinc to react with it. The purpose of venting and draining is to ensure
