Behaviour of structural
components
Displacement of grid or tartan grids.
Where there is a homogenous and
repetitive between at least two basic increments. E.g. 1M + 2M (or) 3/2 M + 3M
Interrupted grids (or) neutral zones
Where there are non modular
interruptions of grids, neutral zones are created to cope with the economics of
building design.

Continuous grid
Where all dimensions in either direction are based on one
increment only.
Superimposed grids
When the modular grid of 100 mm increment is superimposed on a multi-modular grid. building components encourages as far as possible the interchangeable components, whatever the material form or method of manufacture.
simplifies size operations by
rationalizing selling out. Positioning and assembly of building components.
ensures dimensional coordination
between installations equipment, storage units, other fitted furniture, etc) as
well as with the rest of the building.
Modular Grid
A rectangular coordinate
reference system in which the distance between consecutive lines is the basic
module or a multimodule. This multimodule may differ for each of the two
dimensions of the grid.
Types of Modular Grid
There are different types of grid
patterns which are used to locate the positions and dimensions of building
spaces, components and
Major Objective
The principal object of modular
coordinate is to assist the building design, construction professional building
industry and its associated manufacturing industries by standardization in such
a way that building components fit with each other with other components and
with building assembly on site thereby improving the economics of building.
Specific Objective
Modular Coordination thus
Facilitates cooperation between
building designers manufacturers, distributors, contractors and authorities.
In the design work, enables
buildings to be so dimensionally coordinated that they can be erected with
standard components without undue restriction on freedom of design.
Permits a flexible type of
standardization. Which encourages the use of a number of standardized building
components for the construction of different types of buildings.
Optimize the number of standard
sizes of multimodules will suit particular applications. However, if modular
coordination is to be achieves the values of multimodules should not be chosen
arbitrary and only standardized multimodules shall be used. By using
multimodules, it is possible to achieved a substantial reduction in the number
of modular sizes, particularly for components having at least one dimension
equal to one of the dimensions of the functional element of which they are a
part.
A further reduction in the number
of modular sizes may be achieved by means of a general series of multimodular
sizes based on selected multimodules. The international standardizes values of
multimodules for horizontal coordinating dimensions are
3M, 6M,
12M, 80M & 60 M
The
multimode 15M may also be used for special applications.
Aims of Modular co-ordination.
Major objective. Specific objective.
Flexibility
in the arrangement of components.
The modular coordination is
defined as, the basic module is in adopted, the size of which is selected for
general application to building and its components. The value of the basic
module chosen in 100mm for maximum flexibility and convenience. The symbol used
for basic module is M.
1M =100mm
100 mm = 1M = it is international
standard value. Modules
Modules
is a standard unit of size used to coordinate the dimensions of buildings and
components.
Multimodules
Multimodules are standardized

connection. Need for prefabrication
1. Prefabricated
structures are used for sites, which are not suitable for normal construction
method such as hilly region, and also when normal construction material are not
easily available.
2. PFS
facilities can also be created at near a site as is done to make concrete
blocks used in plane of conventional knick.
Structures
which are used repeatedly and can be standardized such as housing storage sheds
godowns, shelters, bus standard security cabins, site offices, fool over
bridges, road bridges. Tubular structures, concrete building blocks etc., are
prefabricated structures.
