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. Murat Serdar KrlThis assumption is valid for service loads. Load and strength are probabilistic variables.
What is the probability of reaching a limit state?
Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresMain assumptions of this methodBetonarme 1 Ders NotlarYrd.
For instance, underthe effect betonarmme a strong ground motion, the assumption of materiallinearity is not valid. Netonarme Serdar KrlIts not a realistic assumption since concrete has not a constant elastic modulus. Post on Dec 12 views. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the beotnarme of structures by using a probabilisticapproach.
Design yield strength of reinforcement steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd. 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 structuresBetonarme 1 Ders NotlarYrd. In case of failure it doesn’t represent the real behavior of the RC sections. Thats why, stresses can not becalculated with reasonable accuracy. Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level.
Design tensile strength of concrete Betonun hesap ekme betlnarme fyd: The little tensile strength of concrete is neglected.
Reinforcement steel is elastoplastic. Betonarme 1 Ders NotlarYrd. Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. The probability distribution of them is usuallyassumed as normal gauss distribution. Murat Serdar KrlWhy do we need a probabilistic approach?
Murat Serdar KrlProbability of reaching or exceeding a limit state of structural system elements is restricted in limit state design.

This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure. Design compressive derx of concrete betonun hesap basn dayanm fctd: Bernouilli-Navier hypothesis is valid. Murat Serdar KrlNM www. Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Concrete – curve is the curve obtained from uniaxialcompression.

Deprem yk Earthquake Load In case of lateral earth pressureH6. Why do we need a probabilistic approach?
Concrete does not take any tension, all tensile stresses are taken by reinforcement. Wind load Rzgar yk In case of earthquakeE0.
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. However, in the design of some vers like water tanks, tensile stress is limited for leak proofing. For instance, a slab which doesnt collapse but vibrates. Derss and material factors arecalled partial safety factors. 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.
