1 Reinforced Concrete Design Lecture no. 1
2 Mechanics of RC Concrete is strong in compression but week in tension. Therefore, steel bars in RC members resist the tension forces.
3 RC Members Reinforced concrete structures consist of a series of individual members. The members interact to support the loads placed on the structure.

7 Types of Loadings Dead loads Live loads Others (wind, snow, earthquake, etc.)
8 Dead Loads
9 Live Loads
10 Properties of Concrete Compressive strength and modulus of elasticity (stress-strain curve) Shrinkage, creep, and thermal expansion
11 Compressive Strength (fc ) The minimum specified compressive strength (fc ) is the strength of concrete after 28 days of curing. Concrete structures are designed to resist all loads during their service life based on the 28-day strength. The tensile strength of concrete is very low, about 8% to 15% of the compressive strength.

14 Factors Affecting Compressive Strength Water/cement ratio Aggregate (type, texture, and grading) Age of concrete Supplementary cementitious materials (e.g. fly ash, silica fume) Moisture conditions during curing Temperature conditions during curing Rate of loading

17 Standard Test Methods Compressive strength test: Cylinder 6 in diameter by 12 high (ASTM Standards C31 and C39) Tensile strength test: 2 methods 1. Flexural test (ASTM C78 or C293) 2. Split cylinder test (ASTM C496)
18 Standard Test Methods (cont d) In the flexural test, a plain concrete beam, 6 x 6 x 30 long is loaded in flexure on a 24 span. The flexural tensile strength or modulus of rupture, f r, is calculated from: f r M = = S 6M bh 2 where, M = moment S = section modulus b = width of specimen h = overall depth of specimen
19 Standard Test Methods (cont d) In the split cylinder test, a standard 6 x 12 compression test cylinder is placed on its side and loaded in compression along a diameter. The splitting tensile strength, f ct, is calculated from: f ct = 2P πld where, P = maximum load in the test l = length of specimen d = diameter of specimen
20 Split Cylinder Test P F 1 F 2 d l P Stress on element Test procedure Fig. 6. Split cylinder test for determining tensile strength of concrete (MacGregor 1988, p.52)
21 Shrinkage of Concrete Drying shrinkage of hardened concrete increases greatly with the amount of water added to the concrete mix. Shrinkage can be harmful if not controlled. It can (1) cause cracks in RC members, (2) induce large stresses in statically indeterminate structures, and (3) lead to loss of prestressing force.
22 Properties of Reinforcing Steels Yield strength (stress-strain curve) Modulus of elasticity

42 Design Procedures Working Stress Design (WSD) = ว ธ หน วยแรงใช งาน Strength Design (SD) = ว ธ ก าล ง
43 Working Stress Design Design is based on working loads, also referred to as service loads or unfactored loads. In flexure, the maximum elastically computed stresses cannot exceed allowable stresses or working stresses of 0.4 to 0.5 times the concrete and steel strengths.
44 Strength Design Design is based on factored loads in such combinations as are stipulated in the code. The computed load effects (Mu, Vu, Tu) must be no greater than the resistance of the member at every section.
45 Strength Design Load effects Resistances For example, M u φm n Moments calculated from a combination of factored loads (U) Strength reduction factor Nominal moment resistance based on properties of member section
46 Combination of Factored Loads U = 1.4D + 1.7L U = 0.75(1.4D+1.7L+1.7W) U = 0.75(1.4D+1.7W) D = dead load, L = live load, W = wind load
47 Strength Reduction Factors (φ) Type of Loading ACI Code Sect ACI Code Appendix C Flexure, without axial load Axial tension and axial tension with flexure Axial compression and axial compression with flexure: a. Members with spiral reinforcement conforming to b. Other reinforced members Shear and torsion Bearing Plain concrete
48 Analysis versus Design Analysis: Given a cross section, concrete strength, reinforcement size, location, and yield strength, compute the resistance or capacity. Design: Given a factored load effect such as Mu, select a suitable cross section, including dimensions, concrete strength, reinforcement, and so on.
