Guide to Design of RCC ColumnsIn my earlier article, we discussed three important thumb rules that are to be followed while making a column layout for any building. They are as follows:. In this article, we will see an example of a residence of which column layout is done keeping the above three thumb rules in mind. The residential villa comprises of 1 and half floors. The builder wanted to save on his budget by making the columns smaller in size. The Columns have been arranged on a iron grid pattern. So there is absolutely no question of zigzag walls and zigzag beams which reducing complications in the structure. Introduction to design of RCC Structures. You can hire me for your structural design need. Contact me. My house total Sq. We plane ground and First floor. I am studying final year civil engineering i have one debut i will attend analysis and design project. I had to line plan but how and where place to put an column sir pls. I m an architect in India and thank u brother to share this …. I am a graduate engineer and I want to make structural design of buildings, but my first question is how can I divide the above given floor slab slab with unaligned columns into number of panels? In other words what is the criteria to consider part of a slab as a panel. You divide the slab with the help of beams. Even if the slab is not exactly rectangular, you can still design it for the entire area. Consider it increased factor of safety. And the adequate beam section for the ground floor. Hi, I want to know how many pillars and columns required for 20 ft X 56ft, house construction, please specify the distance between columns and number of rods and size. Area is Sq. Is is possible to build the building without pillar or coloumn in centre of the parking. Architect has given us the structure design with 11 coloumn out of which 2 are in centre of the parking. Then what would be the width of latak beam minimium to be reqd. After spending several days on internet to understand how to design and build the house i landed on your website. I have something good to share with you based upon learnings as well. I need your expert help to design my house in Lucknow India. Please share your contact details. I tried to avail your services from some of the links you posted but none reaches to a place where i can connect with you. Hi, Sir I am a Civil Engineer and want to ask and consult with you about a technical problem in building, as we know that when we Design the Dimensions of a RCC Column we calculate than the load which is on the top of the column so if we have a column in size of 0. There will be a big issue with the slenderness ratio of the column.

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. Advantages of Kota Stone Flooring. Kota stone flooring is a subtle blend of grandeur and luxury giving the interior and exterior a gorgeous look
For an engineer who is new to designing multi-storey buildings it is important that they follow a logical sequence through the various stages of the design process. Six steps that define this sequence are described below. Rules of thumb are included within each step to help the designer quickly and efficiently arrive at a solution that is sensible for a given set of constraints. Two St. Peter's Square, Manchester. Four Pancras Square, London. Thirty Broadwick, London. Twentytwo, 22 Bishopsgate, London. Many of these stages include aspects of engineering design. A characteristic of steel framed construction is that the constituent parts of the structure are manufactured off-site, with all the quality and speed-on-site benefits that are associated with such a form of construction. An implication of this, however, is that the design must be substantially complete before construction steelwork fabrication can begin. It is therefore important that the designer follows a logical sequence, as going back and revisiting earlier design decisions, once other parties involved have moved on to designing other parts of the building or manufacturing components, can be disproportionately expensive. Some basic choices may have a significant impact on the ease, time and cost of both the fabrication and construction of a steel framed multi-storey building. Keeping fabrication and construction in mind from the start will lead to the best possible solution. The designer should also avoid over-specification, a trivial example being that corrosion protection is not needed when steel components are used in many internal environments. Steel is a versatile material. Because of the different ways that steel beams can be configured, steel structures can be used to create flooring solutions that are competitive for spans ranging from 6m to over 20m. Complexity and lack of familiarity are more likely to result in misunderstandings or misuse, and may cost more. Exotic solutions should only be used for exotic applications that justify the use of non-standard and unfamiliar solutions because of the other attributes they bring. The impact of steel weight on building cost is interesting as there are conflicting drivers. Some things are quantifiable — in many countries labour is more expensive than materials so adopting a larger steel section rather than one that needs labour intensive fabricationfor example of stiffeners, can be more cost effective. Against this argument, using more material may be associated with greater embodied energy and carbon. But the considerations are more complex than that because thicker plates also have greater resistance, for example to localised bucklingso the use of larger sections may:. The extent to which steel weight is minimised will therefore need to be considered on a project-by-project basis taking into account each of the above issues. Closely related to familiarity is standardisation. Although the use of standard member sizes is less important than it used to be, given modern ways of modelling and fabricationthere may still be benefit in reducing the number of different member sizes used on a project. This desire for standardisation goes right down to the steel grade and bolt grades and sizes. Rolled sections should only be specified in grade S steel or higher grade steel to ensure availability as well as performance benefits. However, for the fittings plates used for connections etc. Again, a key is to avoid mixing steel grades for components that look otherwise identical as this facilitates quality assurance. One of the main areas where standardisation is beneficial is the joints or connections as they are traditionally termed in the UK.
