    Continuous
In summary, a continuous slab, also known as a freely supported slab, is a type of concrete slab that is supported by beams or walls on all four sides. This allows for a larger surface area and more evenly distributed weight, making it ideal for larger structures and heavy loads. The slab is able to flex in response to external forces, reducing the risk of cracking or failure. Continuous slabs are commonly used in high-rise buildings, parking garages, and industrial structures due to their strength and stability.

Homework Statement


I was told that for continuous slab , it can be only for 2 ways slab. While for freely supported slab , it can be either 2 ways or 1 way slab.
P/s : for one way slab , the Ly/Lx <2 . For 2 ways slab , Ly/Lx > 2 .

Homework Equations

The Attempt at a Solution


I think it's wrong . The continuous slab can be also one way slab. I have an example here showing that for continuous slab , the slab is one way slab. In this case , Ly/Lx >2 , so , it's 1 way slab.

Any civil engineers have ideas about it ?
 

FAQ: Continuous slab / freely supported slab

1. What is a continuous slab?

A continuous slab, also known as a freely supported slab, is a type of structural system used in buildings and other structures. It consists of a flat, horizontal plate of concrete or other material that is supported by beams or walls on all sides, allowing for a continuous load transfer across the entire slab.

2. How is a continuous slab different from other types of slabs?

A continuous slab differs from other types of slabs, such as one-way or two-way slabs, in that it has supports on all sides rather than just two or three edges. This allows for a more even distribution of loads and can provide greater strength and stability.

3. What are the advantages of using a continuous slab?

One of the main advantages of a continuous slab is its ability to span longer distances without the need for additional support columns or walls. This can result in a more open and flexible floor plan. Additionally, continuous slabs can be more resistant to cracking and can provide better load distribution.

4. What are the design considerations for a continuous slab?

When designing a continuous slab, factors such as the size and shape of the slab, the type and spacing of supports, and the expected loads must be taken into account. The slab must also be designed to resist bending and shear forces, as well as potential cracking.

5. How is the structural integrity of a continuous slab maintained?

To ensure the structural integrity of a continuous slab, proper reinforcement and construction techniques must be used. This includes proper placement and spacing of reinforcement bars, as well as ensuring that the slab is properly cured and free from defects. Regular maintenance and inspections can also help to identify and address any potential issues.
