Construction Documents

Construction documents are the branch of architectural design and a vital field of the architectural process. We must not mistake the construction documents as a schematic design, wherein it involves sketching, model making, and so on. They provide guidance and instructions to the contractor or the subcontractor and they will study the architect’s building design, question the design professionals if needed, create a project manual and schedule for the successful construction of the proposed structure. Construction documentation acquires the detailed building permits and the design-build is initiated.

Can you recheck the k1= 55m from this figure. Thank you so much.

For calculating plastic sectional modulus divide the area with a section that divides the areas
equally and calculate the area moment about this equal area axis.
Let x be the distance of the equal area axis from xx (assuming EAA is in section 1)
IL
150mm
X
2
100mm
EAA
15mm
X
X

Solve for x as below.
area below EAA-A/2
100 X 15+15XX=
3750

15xx= 375
x = 25
x = 25mm
thus equal area axis lies at 40mm from xx
plastic sectional modulus (Z₁)=A₁Xk₁ + A ₂ X K ₂

where A₁,A₂ are areas of sections 1&2=A/2=3750/2=1875mm²
k₁=distance between C.G of the area above EAA and EAA=110/2=55mm
k₂=distance between C.G of the area below EAA and EAA
calculating C.G of the area below EAA
