Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level. Deprem yk Earthquake Load In case of lateral earth pressureH6.

Thats why, stresses can not becalculated with reasonable accuracy. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Murat Serdar KrlThis assumption is valid for service loads.

The little tensile strength of concrete is neglected. In case of failure it doesn’t represent the real behavior of the RC sections. Design tensile strength of concrete Betonun hesap ekme dayanm fyd: Load and material factors arecalled partial safety factors. Design compressive strength of concrete betonun hesap basn dayanm fctd: Murat Serdar KrlWhy do we need a probabilistic approach? Reinforcement steel is elastoplastic. betonwrme

For instance, a slab which doesnt collapse but vibrates. What is the probability of reaching a limit state? Post on Dec 12 views.

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. Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach. For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid.

Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. Home Documents Betonarme 1 Ders2 Ing.

Probability 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 nohlar case of failure. Concrete does not take any tension, all tensile stresses are taken by reinforcement. Load and strength are probabilistic variables. Live load Hareketli yk T: The probability distribution of them is usuallyassumed as normal gauss distribution.

The dfrs 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 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.
