A Reinforced Concrete Slab is the one of the most important component in a building. It is a structural element of modern buildings. Slabs are supported on Columns and Beams.
RCC Slabs whose thickness ranges from 10 to 50 centimetres are most often used for the construction of floors and ceilings.
Thin concrete slabs are also used for exterior paving purpose.
RCC Slab Construction
In many domestic and industrial buildings a thick concrete slab, supported on foundations or directly on the sub soil, is used to construct the ground floor of a building.
In high rises buildings and skyscrapers, thinner, pre-cast concrete slabs are slung between the steel frames to form the floors and ceilings on each level.
Convention centre are often a means to represent ethos of a particular country, perhaps, even an expression of myth of a particular community and their traditions. A place which can provide the essential, platform for exchange of ideas. In an urban context, where cities witness rapid growth and development, a convention centre caters the need of stage where new innovative ideas can be sold, shared, felt and experienced. This can be in the form of exhibitions, workshops, seminars, conferences serving the purpose of both the industrialist and the consumer. The best example is the Pragati Maidans.

Case Studies
Pittsburg Convention Centre
The largest first gold LEED certified building located near the Alleghemy river which was also appreciated for having the concept similar to that of the suspension bridges in that city. The planning thus offered dramatic vistas overlooking the river onto the historic downtown.
Simply supported slabs are supported on columns or stanchions. They have support on all four sides.
Simply Supported Slab
Simply supported slabs are classified as One way slabs and Two way slabs.
One way slabs bend in one direction only and transfer their loads to the two support beams in opposite directions. Their main steel in on shorter span length. L/B ratio is generally less than 2.
Two way slabs bend in both directions, and transfer their loads and stresses on all four sides. L/B ratio is equal to or greater than 2.
Simply supported slabs don’t give adequate provision to resist torsion at corner to prevent corner from lifting.
The maximum bending moment will be given if the slabs are restrained. But atleast 50% of the tension reinforcement provided at the mid span should extend to the support. The remaining 50% should extend to within 0.1Lx or Ly at the support as appropriate.
You can use a free app to design simply supported RCC Slab panel.
RCC Slab Design depends on the on the dimensions of the slab after which the slab is termed as a one-way slab or a two-way slab…
In the design of RCC structures, Column Design and Beam Design are to be done before we start with RCC Slab Design…
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.

Columns support floors in a structure. Slabs and beams transfer the stresses to the columns. So, it is important to design strong columns.
Reinforced Cement Concrete Column Plan and Section
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.
RCC Structures are nothing but reinforced concrete structures. RCC structure is composed of building components such as Footings, Columns, Beams, Slabs, Staircase etc.
These components are reinforced with steel that give stability to the structure. Staircase is one such important component in a RCC structure.
Dog Legged Stair | Staircase design
In this article, we will discuss different types of staircases and study the dog-legged reinforced cement concrete staircase design.
Structural Engineering and Architecture are two different sciences that are inter-related. Structural Designing deals with the study of design of steel in a structure i.e., the internal skeleton of the structure that helps to keep the structure durable, sound and stiff.
Whereas Architectural Design deals with design of spaces meant for a particular function. It helps to create ambient environment that is pleasing to eye. The Architect designs the building keeping all the functional aspects in mind that are to be incorporated into the design and then they are executed by a Civil or Structural Engineer.
Inter-relationship of Architectural Design and Structural Design
The structures and structural members are designed to meet the functional and structural aspects. Both the aspects are inter-related. The functional aspect takes into consideration the purpose for which the building or the structure is designed. The functional aspect includes the determination of the amount and arrangement of space necessary for the structure.
Structural design is the science of studying the Mechanics of a structure. Designing the skeleton of a building determines the real strength of the structure.
If the structure is externally beautiful and internally weak, it results into dramatic structural failure.
Structural Framework in a building
In this article, we are going to discuss in detail about the “Various Methods of Structural Design”.
All parts of a structural steel framework of a structure shall be capable of sustaining the most adverse combination of dead loads, the prescribed super imposed roof and floor loads, wind loads, seismic forces where applicable, and any other forces or loads to which the building maybe reasonably subjected without exceeding the permissible stresses.
The following methods may be employed for existing steel framework:
Lighting or illumination is done to achieve some ambient and aesthetic effect. Lighting enhances the beauty of the structure. The kind of lighting to be done depends on the kind of space.
Lighting done to illuminate the interiors and enhance the aesthetics is different from the lighting done in the exteriors, it could be done to illuminate the external facade of the building or to enhance the aesthetic appeal of the landscape at night.
Task Lighting
Lighting can be classified into various different methods of lighting. It can be broadly classified as :
When people talk aboutGreen buildings, it is assumed they are eco-radical tree-huggers. But its true. Green building technology can really help achieve sustainable development by reducing energy consumption to a large extent and improving the return on investment by reducing maintenance.
When considering the economic benefits of smart technologies one must include many factors, such as health cost, future economic stability, quality of life and costs of operation.
In India, Thiagaraj Convention Center in Chennai is one such place where green building technology has been extensively used. Many of the building techniques can easily be adapted to existing buildings. For example, the transition from incandescent light bulbs to compact fluorescent light bulbs can lead to energy savings of upto 75% of costs. The small increase in initial costs to purchase the bulbs would easily be recouped many times over by the savings and extended life of the new bulbs.
“A green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building.”
As the world reels under the stress of economic recession and Peak oil, efforts are being made to minimize the use of energy, to maximize return on invested resources by recycling and optimum use of natural resources. Such efforts have culminated into the new Green building movement across the planet.
Brief Introduction of the Project
A contemporary convention centre having state of art facilities, using modern building techniques and energy efficiency as the prime design parameters.
