PHASES OF STRUCTURAL DESIGN WORKS

-


 Structural Design is the design technology which aim at determining the appropriate sizes and materials of structural members that form a structure, the determined sizes and material should formulate safe and serviceable structure at acceptable cost (minimum cost).

PHASES OF STRUCTURAL DESIGN WORKS

This explains different stages followed for accomplishment of structural design work of different structures either whole or member of the structure.

The following are the involved stages

  • Preliminary structural design

In this phase the sizes (dimensions) of different structural members forming structure are proposed in approximate by referring experience and code requirement.

The proposed dimensions of the members are the one which used in next stage of design that is load estimation.

  • Estimation of loads

This involved the estimation of amount of loadings that the structure will have to carry on its life time; this includes wind loads, live loads and self weight.

  • Structural analysis

In structural analysis we will have to determine the effects of loadings to the structure, this involves the determination of internal forces or internal resistance of the structural members and deflection at different points of structure.





  • Safety and serviceability check

In this phase the sizes and materials of structural members are checked, if they can withstand the effects of loadings which are internal forces and deflections found in analysis phase.

The safety and serviceability checking of structural members on loadings are done per standard design code requirements of certain country.

If the requirements are satisfied then the design drawings and construction specification are prepared and construction phase starts.

  • Revised structural design

If the requirement was not met in safety and serviceability check phase, this phase comes where by structural member dimensions and materials are modified.

 So we will have structural members of different properties, this makes us to repeat phases from structural analysis to know the loading effects to modified members.

The repetition proceeds up to safety and serviceability check until the requirements are satisfied, so that the structure to be constructed can be safe and serviceable.

HOW TO FIND THE MEAN GIRTH OF THE SIMPLE BUILDING

Mean girth of building , this is the centerline perimeter or circumference of the building, which describes length of the building. The following text show how to find the mean girth of simple building plan shown below for superstructure walling which can help in quantity determination of different materials to be applied for paint work, plaster work, blocks or brick work. Important Terms 1. External Dimensions.   These are dimensions measured from      external surface of the building's walls, these always show the extent of building on plot. 2. Internal Dimensions. These are dimensions measured from internal surfaces of the building walls, these always show sizes of rooms. 3. Corner. These are interconnection or points where two non colinear walls meet. 4. Recesses. There are the partition or adjoining walls which forms rooms or which were not considered in exterior girth of building determination. Timesing Dim

HOW TO CALCULATE AMOUNT OF  MORTAR  PER S.Q.M FOR BLOCK WALL The amount of cement paste required as mortar per square meter can be calculated through the following steps 1.       Knowing the dimension of the blocks to be used for construction. Here, let’s say we use the cement concrete block of size 150 x230 x450 where by 150 s the thickness of the wall. These dimension s (all dimension are in mm) help to find the area of one block forming wall surface as follows Area of one block = 230 x 450                              = 103,500mm 2 2.        Knowing the new dimension of blocks with cement mortar. New dimension of concrete block means the height and length of a block with the thickness of mortar which is 15m, then the new height id 245mm and new length is 265mm From these new dimensions we can get new area of one cement concrete block as follows Area of one block = 245 x 465                              = 113,925mm 2                              =1.14 x

The number of blocks required for wall can be calculated from the area of the wall which will be constructed by the block of certain size. The mean girth of the simple obtained as calculated from previous post is 28.85m The common (standard) size of the conc. block is 150 x 230 x 450; the wall length (mean girth) of building is multiplied by the height of the walls to find the total  surface area of wall, for a wall of height 2.8m with the opening as shown in the table below The table below shows windows and doors schedule for doors and windows used   Schedule for windows used PORTIONS WIDTH(m) HEIGHT(m) NUMBER(m) AREA(m 2 ) A 1.50 1.50 3 6.75 B 1.50 1.50 2 4.50 C 0.7 0.7 1 0.49 1.00 1.50 1 1.50 D 1.50 1.50 1 2.25 1.00 1.50 1 1.50 Total Area of All Windows
