How to design the reinforced concrete wall

You have to design the Reinforced concrete wall similar to a compression member. Reinforced concrete wall is suitable when there are no beams and load transmitted from the slab is massive or the density of the masonry wall is restrained.

RCC Wall is segregated as follow:
• Plain concrete wall, when rein. < 0.4%
• Reinforced concrete wall, when rein. > 0.4%

Load from slab is transmitted as axial load to wall. When depth is greater, it is known as RC wall. Design is identical to a RC column, breadth is similar to the density of wall and depth is equivalent to 1m. The design of RCC Wall is based on the following factors.
• Axially loaded wall
• Axially loaded with uniaxial bending

Categorization of concrete walls:

1. Plain concrete wall
2. Reinforced concrete wall

Under plain concrete wall, the reinforcement included is under 0.4% of c/s. In reinforced concrete wall, the proportion of employed steel is in excess of 0.4% and is designed in the same way as reinforced concrete columns. Slenderness ratio is equivalent to minimum of (l/t or h/t), where, l denotes effective length of wall, h stands for effective height of wall, t stands for thickness of wall. When < 12, the wall becomes short and if > 12, the wall becomes slender.

Braced and Unbraced Concrete Walls:

Braced: If cross walls are arranged for the walls so as to they can bear lateral load and 2.5% of vertical load, then the wall is defined as braced. If not, the wall is called as unbraced wall.

Note: Other walls under special cases are,
i) Cantilever wall
ii) Shear walls – To withstand lateral loads [Handle flexure created because of lateral loading on the structure, depth is allowed along the transverse direction]

Download truss design spreadsheet

This estimating spreadsheet is specifically created for designing truss. By using this spreadsheet one can design light gage truss on the basis of AISI S100/SI-10 & ER-4943P.

The following design criterion is required for truss analysis.

The intermediate, finite element analysis contains shear deformations with E & G equivalent to 29500 ksi & 11300 ksi.

There are various rotations at similar joint of web to chord, since web pinned to continued chord.

Top chord shall be affixed to sheathing prior to inclusion of vertical load.

This spreadsheet will be useful for defining joint deflections with finite

Various aspects of Design Loads

This construction video is recorded on design loads. Design loads are essential while designing any building or civil structure. One can learn types of design loads and it’s various categories. You will also be familiar with dead loads values with adherence to the IS code 875-1987 part-1.

In architecture and engineering term, design load stands for the highest amount of stress that a structure has to withstand. Weight is one of the most important factors that should be taken into consideration for making calculation. Beside, weight, design load calculations should also include other types of forces that a structure has to undergo.

As for instance, bridges and tall buildings should have the capability to withstand strong winds as well as supporting their own weight along with the weight of people and objects that are on them or within them.

Perfect calculation of design load is very important to ensure that a structure is secured. If the design load is not computed, stability of structures, or even segments of structures, can be hampered. Unstable structure may collapse which can be deadly.
