Staadpro-Structure Geometry and Coordinate System

Particular structure is an assembly of components such as beams, columns, slabs, plates etc. Typically, modelling of the structure geometry consists of two steps:


 -Identification and description of joints or nodes.

-Modelling of members or elements through specification of connectivity between joints.

Infiltration vs Permeability


                   Infiltration refers to the downward entry or movement of water into the soil surface. It is a measure of the rate at which soil is able to absorb rainfall or irrigation. It is determine by a soil characteristics including ease of entry, storage capacity, and transmission rate through the soil. 


                      It is measure of ability of a porous material to allow fluid to pass through it. High permeability will allow fluids to move rapidly through rocks. Permeability is affected by the pressure in a rock.

Staadpro-Define Structure type

First define which type of structure it is:

Space type:

                 is the structure where the geometry , loading cause the structure to deform in all 3 global axes (X, Y and Z).

Plane type:

                   is the structure where the geometry , loading and deformation is restricted to global X-Y plane only.

Concrete vs stone, timber and steel

     Why Concrete is superior to stone, timber and steel ?

    • Stone, timber and steel cant be fit to any mould but concrete can fit to any mould.
    • Structure made of stone, timber and steel have several joints but different element of concrete  can be cast monolithically.

    Circular Beam

    Why we are not constructing circular beam ?

    In case of beam all the stresses are at top and bottom. Circular area is maximum area at center, where we don't have any bending. To overcome stresses we need to provide steel at top and bottom. but in case of circular beam its not possible to provide steel at top and bottom.

    Retaining wall vs Buttressed retainning wall

    What is the difference between Retaining wall and Buttressed retainning wall ?

    Main difference in buttressed retaining wall is we provide thin slab at some intervals to tie base slab and stem in order to reduce the shear force and bending moment.
