Experimental and Numerical Assessment of Flexural and

2020/7/7The paper presents the results of flexural and shear tests up to failure on full-scale hollow-core slabs (HCS) having a depth of 500nbsp;mm. A detailed non-linear 2D finite element model is also developed to predict the stress distribution and crack pattern within the slabs, providing a well match with experimental results. Experimental and numerical results are compared with analytical Get price

What is Precast Concrete? What Are the Advantages?

Foundations: Precast concrete is used to create entire buildings — more about that below — but in cases where it isn't utilized for the entire building, it may still be used for the foundation. Many residential homes and other buildings have precast concrete foundations, regardless of what is used for walls and floors in the rest of the building. Get price

Prestressed Concrete Bridges

When used horizontally as a slab or beam, concrete can typically span only short distances before it begins to crack and fail unless it is made thicker. The depth and weight of a plain concrete beam soon become too large and impractical for longer horizontal spans required in buildings and bridges. Get price

How concrete is made

Although the concrete itself is not strengthened, structures built of reinforced concrete can better withstand bending, and the technique was used internationally by the early twentieth century. Another form of strengthened concrete, prestressed concrete, was issued a U.S. patent in 1888. Get price
