The modulus of the cross-section will be then equal to the modulus of concrete. The whole expression for the rectangular cross-section which depth is h and width is b will be: Acs=bxh+(1-(Es/Ec))xAs.

test the lower the modulus of elasticity—wet concrete is stiffer al-though often weaker); and the method of obtaining the deformations (strain gage, mechanical compressometer, transduc-ers, etc.). In view of the possible variability of experimental data on modulus, it is Modulus of rupture = 2.38 MPa. Comments: For a long time the tensile strength has been measured by means of modulus of rupture test. It gives indirectly tensile strength of concrete sample. The modulus of rupture obtained by this method is very close to the values given by double punch and split cylinder test. Sample after the test: concrete compressive strengths are close to 4 ksi (28 MPa). The use of these formulas with higher-strength concrete should result in more realistic camber predictions and lower prestress loss estimates. The following sections present the background and recom-mendations for prediction of the modulus of elasticity, Figure 1.

The following sections present the background and recom-mendations for prediction of the modulus of elasticity, Figure 1. A good, normal concrete mixture has an E-modulus of 25.000-30.000 N/mm2. Please note that the higher the E-module, the higher peak stresses will become!

If you get a really weak E-module, it’ll bend more (perhaps more than you’d like to).

assuming all the materials are concrete. You can change material as per your requirement also. 2. Floor load generation over curved beams
As concrete is a heterogeneous material. The strength of concrete is dependent on the relative proportion and modulus of elasticity of the aggregate. ACI 318–08, (Normal weight concrete) the modulus of elasticity of concrete is, Ec =4700 √f’c Mpa and IS:456 the modulus of elasticity of concrete is 5000√f’c, MPa. The main factors which may affect the values determination of modulus of elasticity are, Modulus of elasticity of concrete (Ec) is defined as the ratio of the applied stress to the corresponding strain. Not only does it demonstrate the ability of concrete to withstand deformation due to applied stress but also its stiffness.

Modulus of Elasticity - is a measure of stiffness of an elastic material.

The modulus of elasticity of a concrete material is calculated automatically according to the Eurocode (EN 1992-1-1). This value cannot be edited when the option ‘Calculated depended values’ is checked. If the option ‘Calculated depended values’ is unchecked, the value of the E modulus can manually be edited:
