Because of its many advantages—particularly the great freedom that it offers in terms of shapes, its high durability, and its cost-effectiveness—reinforced concrete is without a doubt the most commonly used construction material in the world. Everything points to it...
Shrinkage is a phenomenon by which the concrete undergoes strain caused by the decrease in the volume of concrete due to drying at constant temperature. Shrinkage strain generally develops during the first two to three years after casting of concrete...
2. Basic Concepts for Design
Cross-sectional dimensions of reinforced concrete beams, slabs, columns, and walls are generally selected in multiples of 10 mm, except for thin slabs where they may be in multiples of 5 mm. Allowable tolerances for cross-sectional dimensions of beams and...
3. Behaviour of Beams and One-Way Slabs in Flexure
Two distinct zones can be observed: a compression zone and a tension zone, separated by the neutral axis (zero stress). Given its low tensile strength (assumption A2), concrete can resist tensile forces until it is cracked. Thereafter, these forces are transferred...
4. Design and Verification of Beams and One-Way Slabs in Flexure
Several reasons may lead engineers to consider sections with both tension and compression reinforcement (so-called doubly reinforced sections). Examples include a) cyclic loading (such as earthquakes), b) constructive compression bars...
5. Shear Design
The main objective of providing transverse reinforcement, or so-called shear reinforcement, is to control the width of inclined cracks when they occur (Figure 5.1f). These shear reinforcements may be of different shapes, as described in...
Torsion can be due to a) the disequilibrium in statically determinate structures, where a torsional moment develops to maintain equilibrium between external and internal forces (this type of torsion is called equilibrium torsion (Figure 6.1a)), or b) the incompatibility...
7. Bond Development and Splice Reinforcement
When designing RC structures, it is generally assumed that steel and concrete are intimately linked at their interface through a so-called bond. This assumption is of paramount importance. In flexure, for example, the lack of bond will prevent the force in the...
8. Approximate Frame Analysis Method for Continuous RC Beams and One-Way Slabs
RC building structures (beams, columns, floors, and slabs) are generally cast in place and are therefore considered as monolithic. These structures behave therefore as tridimensional statically indeterminate systems (Figure 8.1a). Their analysis is often long...
9. Two-Way Slabs on Stiff Beams or Walls on Four Sides
When the negative moment of one supported side of a continuous slab differs by more than 20% from that of the other side, the difference must be redistributed over the two adjacent panels according to their respective stiffnesses. Should the difference...
10. Two-Way Slabs: Direct-Design Method
In the case of two-way slabs not resting on rigid supports, as defined in Chapter 9, the direct-design method can be a wise choice. This method, described in Clause 13.9 of the standard, is a simplified version of the equivalent-frame method. It is based on empirical...
11. Compression Members: Braced Columns
Columns are rarely subjected to concentric compressive loading. Normally, they are subject to compression resulting from vertical loading and flexural moment caused by one or more of the following: a) continuous moment transmitted from the floor...
Foundation footings transfer loads from vertical bearing elements, such as columns and walls, to the soil. Footing dimensions are generally greater than those of the supported elements to distribute and reduce the induced stresses on the soil. They are therefore...
