Load and material factors arecalled partial safety factors. However, in the design of some structures like water tanks, tensile stress notlarr limited for leak proofing.

For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. Deprem yk Earthquake Load In case of lateral earth pressureH6.

Betonarme 1 Ders NotlarYrd. Murat Serdar KrlThe probability of collapse is assumed to reduce to predetermined value by increasing characteristic loads with load factors f anddecreasing the characteristic strength with material factors m.

Reinforcement steel is elastoplastic. For instance, a slab which doesnt collapse but vibrates. In case of failure it doesn’t represent the real behavior of the RC sections.

Murat Serdar KrlWhy do we need a probabilistic approach? The little tensile strength of concrete is neglected.

Probability of reaching or exceeding a limit state of structural system elements is restricted in limit state design. Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresMain assumptions of this methodBetonarme 1 Ders NotlarYrd.

Murat Serdar KrlNM www. Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresBetonarme 1 Ders NotlarYrd. Concrete does not take any tension, all tensile stresses are taken by betonrme. Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Concrete – curve is the curve obtained from uniaxialcompression.

The probability distribution of them is usuallyassumed as normal gauss distribution. Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach.

Post on Dec 12 views. Thats why, stresses beetonarme not becalculated with reasonable accuracy. Murat Serdar KrlLimit state design Limit durumlara gre hesap Limit state defines a particular state of a structure which may becollapse or loss of function, either partial or total.

What is the probability of reaching a limit state?

Structures mustbe designed so that the probability of reaching a limit state is lowerthan betonarm level. Bernouilli-Navier hypothesis is valid. Murat Serdar KrlProbability of reaching or exceeding a limit state of structural system elements is restricted in limit state design. Murat Serdar KrlIts not a realistic assumption since concrete has not a constant elastic modulus. Wind load Rzgar yk In case of earthquakeE0.

Design yield strength of reinforcement steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd. Design tensile strength of concrete Betonun hesap ekme dayanm fyd: Murat Serdar KrlThis assumption is valid for service loads. Load and strength are probabilistic variables. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Both steel and concrete are assumed to be linear elastic and Hooke Law is valid.

Design compressive strength of concrete betonun hesap basn dayanm fctd: The first stage of design making design of a cross-section for theultimate limit state and the following step is checking the serviceabilityrequirements deformations and cracks. Why do we need a probabilistic approach?
