Column Layout for a Residence | Civil Engineering

I highly recommend use of advanced structural design software like ETabs or Staad Pro for design of structures. This is very important. There are so many variables in design of a structure that no minimum standards can be accurate. But I would still recommend use of professional software. Every structural designer should learn these software. Use of manual methods is outdated. Manual method is only used for checks. Real design is done with the help of computers, with very advanced design concepts like pushover analysis, seismic analysis, wind loads simulation and many advanced methods. You can hire me for your structural design need. Contact me. In this article, I will discuss the minimum standards that can be followed for the design of RCC structural components of a structure, such as columns, beams, slab and foundation. We will also discuss the minimum safe standards for the reinforcing bars that are to be used for the design of the above mentioned Structural Components. I have designed hundreds of buildings, and never had the misfortune of any structural component ever failing due to loads. I always use M20 grade concrete for construction, as it is the minimum recommended grade of concrete is IS But there are a lot of other factors involved. Thumb rules for making a Column Layout. I generally use a minimum of 4 bars, with 2 bars of 12 MM thickness in the bottom of the beam, and 2 bars of 10 MM at the top of the beam. I maintain a concrete cover of 40 MM. I recommend use of M20 grade of concrete 1 part cement : 1. It is recommended to go to depths up to had strata. Columns : 4 bars of 12mm steel rods FE Beams : 2 bars of 12 mm in the bottom and 2 bars of 10 mm on the top. In a 1m X 1m footing, this would consist of 6 bars of 8 mm on both portions of the steel mesh. What should I do now? Should I break the roof and reconstruct? I would strongly recommend that you get a certified civil engineer and get the structure assessed before taking any step. I got my buolding built by a contractor who did not seem to have consulted a structural or a civil engineer. The dimension of the hall is 32X33 feet. He has raised de walls with three concrete belts one at de foundation, second at de lindal level 7 ft and 3rd at de roof level.

Rcc Column Size For 2 Storey Building

A column is a very important component in a structure. It is like the legs on which a structure stands. It is designed to resist axial and lateral forces and transfer them safely to the footings in the ground. You can manually calculate the superimposed loads on a column in a structure using a simple process outlined in this linked article. You can hire me for your structural design need. Contact me. Columns support floors in a structure. Slabs and beams transfer the stresses to the columns. So, it is important to design strong columns. A column is defined as a compression member, the effective length of which exceeds three times the least lateral dimension. Compression members whose lengths do not exceed three times the least lateral dimension, may be made of plain concrete. The axial load carrying capacity of a column is deduced from the formula. Please see the link for formulas to calculate axial loads in columns. I would recommend using advanced structural design software like ETabs or Staad Pro for design of structures. Column design does not depend only on axial loads, but also on many other factors. There are bending moments and tortional forces induced due to beam spans, wind loads, seismic loads, point loads and many other factors. In this article, we are going to discuss in detail the basis of classification of columns and different types of reinforcement required for a certain type of column. The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio. Thumb rules for designing a Column Layout. Example of a Column Layout of a Residence. Consequences of Wrong Structural Design. Can you please tell me how will we calculate the leg of the RCC column,or it depents on development length. Hello I have a site and have involved few architects to design the building. I need to know the structure design compatability. I am buildin an office space c to c measurements are more than 26 feet. There is no such thing as thumb rules…You must see a civil engineer if you want to get a structure designed. Structural engineering is a 4 year course. People work hard to become good civil engineers. Of course you must have found a contractor who would advise you that you dont need a civil engineer but trust me the building quality will be absolutely disastrous. You build a house once in a lifetime, invest wisely. Get experts involved. Your dream house should not look like a piece of trash.

In this article, we will go through the essential thumb rules to be followed for giving a column layout. Of-course columns have to be designed in accordance to the total forces acting on the structure, but apart from that, it is essential for every Civil engineer and Architect to remember a few thumb rules so that they are prevented from making mistakes. You can hire me for your structural design need. Contact me. The size of the columns depends on the total load on the columns. There are axial loads and lateral loads. Large beam spans induce bending moment not only in the beams, but also in columns which are pulled by the stresses in the beams. It is important to use advanced structural design software like ETabs or Staad pro. I highly recommend every structural designer learn these software. The thumb rules are for general designing in very small projects. You can never go wrong with strong columns. I also recommend use of M20 grade concrete for the structure ratio 1 part Cement : 1. I recommend use of 8 MM stirrups at a distance of MM center to center throughout the length of column. There are a lot of other considerations, but this is just a thumb rule. For the above column setup, a span of up to 5 meters is quite safe. There are other considerations like secondary and tertiary spans, point loads and wall loads which have to be considered. It is complicated, but thumb rules can work if the structure is simple. It is always recommended to use structural design software like ETabs or Staad pro for design. In a beam of up to 5 meters length, secondary spans of up to 4 meters, wall loads of up to 8 kN per running meter, I can use steel as below. Placing of columns depend completely on the plan. A planner has a very important job. A grid column placement is always preferred in order to reduce point loads and unnecessary complications while construction. This reduces the cost of construction as well as time required for construction. Beams which have continuity with other simply supported beams have reduced bending moments, and thus require less steel and concrete depth to be safe. Columns have to be connected with each other for smooth transfer of loads.

The vertical support which is free from all sides taking the load of beam slab etc. Column is constructed with the help of steel bars and cement concrete. The size, cement concrete ratio and numbers of steel bars with their diameter are available in structural drawings which are designed according to the load born by the column and factor of safety. Cement Concrete. In the construction of building work, there is need of various types of building materials which are used during the construction work at different stages. According to structural drawing, cement concrete of different qualities or mix are used in the building at different stages according to the type of building. Ready Mix Concrete. This article tells you about ready mix concrete, preparation of ready mix concrete and its benefits. Shuttering or Form work is most important part of any construction project. Steel, Wood or other likewise material is us. Mild Steel Bars in Cement Concrete. Mild steel bars in reinforced concrete are one of the exceptional building materials. Reinforced concrete requires very strong steel bars. This article provides a brief view of steel bars in cement concrete work. Every process needs proper guideline and expert person or team to manage in construction or in any field. How to get more strength with same quantity of cement? The same cement can provide better coating to particle and hence more strength when coarse aggregate is used. What is cement concrete and which are various ratios according to the site requirement? The cement concrete is a mixture of cement fine aggregate, coarse aggregate and water. What is Reinforced Cement Concrete? Concrete is strong in compressive stress but is weak in tensile stress. What quantity of water is required for cement concrete? For general work the different materials required for cement concrete mix is measured loose through measuring box by volume for 1 cement bag at one time. Cement Concrete Raw Material. Read points should be kept in mind while collecting raw materials for cement concrete in construction work. What is concrete cover for reinforcement? The concrete cover for steel bar is very much necessary to protect the steel against corrosion rusting and to provide resistance against fire. Concrete Mix Ratio. Compressive strength is the most important property of hardened concrete. It can be measured easily on standard sized cube 15 cm and is often taken as an index of the overall quality of concrete.
