Assignment No. (1): Loads on Columns
-------------------------------------------------------------------------------------------------------------------------------
For The Architectural Plan Shown Below, the following is required:
1) Draw the Architectural and the Structural Plan (Scale 1: 50)
Showing the arrangement of columns and beams.
2) Draw Plan for columns & Axis only (Scale 1: 50).
3) Calculate the Columns Reactions in the Ground floor, Using (Beam Reaction Method).
Choose only (6) Columns [ they should be as follows ] :
i. ( 2 ) Interior Columns.
ii. ( 2 ) Edge Columns.
iii. ( 2 ) Exterior Columns.
Given Data:
A) Structural Elements Dimensions:



Slab thickness : 120 mm.
Beams cross section: 600 x 200mm (that carry the brick walls of thickness 200mm)
& 600 x 120 mm (that carry the brick walls of thickness 100 mm).
All Columns have the same dimensions which is ( 600 x 300 mm ).
B) Loads:
 Weight of covering material = 1.50 kN/m2
 Live Load = 2.00 kN/m2.
 Weight of brick walls for 100 mm = 2.50 kN/m2
 Weight of brick walls for 200 mm = 3.50 kN/m2
C) Building Information:
 The building consists of Ground Floor + Four Typical Floors.
 Floor Height = 3.00 m.
