it is the modulus of elasticity, rather low for concrete compared to steel.
it can be estimated using equation E=3320(Fc)1/2 + 6900
Fc being the compressive strength

What is relative stiffness of concrete?
Relative stiffness of concrete refers to the ratio of its stiffness to that of another material, typically the reinforcing steel within a composite structure. It is an important parameter in structural engineering, as it influences the behavior of reinforced concrete under loads, particularly in terms of deflection and cracking. High relative stiffness indicates that the concrete can effectively resist deformation compared to the reinforcement, leading to better load distribution and structural integrity. This concept is essential for optimizing the design of concrete structures to ensure safety and performance.

What is the stiffness of concrete beam?
Stiffness is defined as the ratio of load per unit deformation.
How do you calculate natural frequency of a concrete slab?
The natural frequency of a concrete slab can be calculated using the formula f = 1/(2π) * sqrt(k/m), where f is the natural frequency, k is the stiffness of the slab, and m is the mass of the slab. Stiffness can be determined by the material properties and geometry of the slab, while mass can be calculated by multiplying the volume of the slab by its density.
What is stiffness factor?
the stiffness of a vehicle structure in a crash
Is concrete isotropic or anisotropic?
Concrete is typically considered anisotropic because its properties (e.g., stiffness, strength) can vary depending on the direction in which they are measured. This anisotropy is due to the arrangement of its constituents (i.e., aggregate particles, cement matrix) which can lead to differing mechanical behavior in different directions.
What is the effect of varying percentages of steel on the moment of resistance of RCC Section?
With varying percentage of steel moment capacity varies. Since moment capacity is directly related to the stiffness of the concrete therefore more is the steel percentage in the concrete more is fc' and in turns more is the moment carrying capacity.
Is stiffly an abstract noun?
No, the word 'stiffly' is not a noun at all.The word 'stiffly' is the adverb form of the adjective 'stiff'.The noun form of the adjective stiff is stiffness, a concrete noun, a word for a physical quality.
If the length of a spring is halved the stiffness becomes?
If the length of a spring is halved, the stiffness remains the same. Stiffness of a spring is determined by its material and construction, not by its length. Cutting the length in half does not change the material properties that govern stiffness.
What is the stiffness of beam?
Stiffness is defined as the ratio of load per unit deformation.
What part of speech is the word stiffness?
A noun of the abstract type.
