What are the advantages of continuous members in prestressed concrete structures?
Advantages of continous members
- TOPIC 1 ADVANTAGES OF CONTINOUS MEMBERS.
- EVEN DISTRIBUTION OF MOMENTS • Between center of span and supports • Lesser span moments • Longer spans.
- REDUCTION OF SIZE • Vertical load carrying capacity is more • Lighter structures • Economical.
What are the disadvantages of beams?
Disadvantages of Beam Bridges
- Beam Bridge contains forces, which are much larger than the load, and it needs to be relatively massive.
- Beam Bridges have a limited span and do not allow large boats or vehicles to pass underneath.
- Mostly heavy boat traffic or large ships cannot pass underneath.
What is the difference between simply supported slab and continuous slab?
A simply supported slab is one type of slab with its ends simply supported on two walls or beams free to bend at the ends without any restraint unlike a fixed beam. A continuous slab has number of supports at series manner. In other words a continuous slab has more than one span.
What is the advantage and disadvantage of concrete?
Advantages and Disadvantages of concrete
| Advantages of concrete | Disadvantages of concrete |
|---|---|
| It possesses high compressive strength to withstand a huge amount of load. | It has low tensile strength and hence cracks are developed. |
What are the advantages and disadvantages of the use of prestressed concrete in construction?
It requires high strength concrete and high tensile strength steel wires. The main disadvantage is construction requires additional special equipment like jacks, anchorage, etc. It requires highly skilled workers under skilled supervision.
What are the advantages of continuous beams over simply supported beams?
Therefore, it has all the advantages that indeterminate structures have over determinate structures (Simply supported beam in this case). • A continuous beam has lesser maximum positive bending moment than a simply supported beam. • A continuous beam has lesser maximum deflection than a simply supported beam.
What are the advantages and disadvantages of concrete?
However, there are advantages and disadvantages associated with this material. For example, while concrete becomes stronger and more durable with time, it is susceptible to water and freezing temperatures, meaning that water can seep into cracks and cause damage to the concrete.
What are the advantages and disadvantages of continuous bridges?
Advantages 6. Disadvantages. Continuous bridges are more economical but lack simplicity in the design procedure. These structures have the relative advantage that their designs are simple and do not involve any complicated analysis but the main drawback is that such structures are generally comparatively costly.
What are the advantages of pre-stressed concrete over reinforced concrete?
Pre-stressed concrete offers more advantages than reinforced concrete, which are as follows; 1) The cross-section is utilized more efficiently in pre-stressed concrete as compared to reinforced concrete. 2) Pre stressed concrete allows for a longer span.
