Deprem yk Earthquake Load In case of lateral earth pressureH6. Load and strength are probabilistic variables. Betonafme compressive strength of concrete Betonun karakteristik basn dayanm fctk: This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.

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: Reinforcement steel is elastoplastic.

Murat Serdar KrlWhy do we need a probabilistic approach? Concrete – curve is the curve obtained from uniaxialcompression. Probability of reaching or exceeding a limit state of structural system elements is restricted in limit state design. Design yield strength of reinforcement steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd.

Thats why, stresses can not becalculated with reasonable accuracy. The little tensile strength of concrete is neglected. Concrete does not take any tension, all tensile stresses are taken by reinforcement. Live load Hareketli yk T: Murat Serdar KrlIts not drs realistic assumption since concrete has not a betojarme elastic modulus.

Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Load and material factors arecalled partial safety factors. Post on Dec 12 views.

Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach.

Murat Serdar KrlNM www. Murat Serdar KrlProbability of reaching or exceeding a limit state of structural system elements drs restricted in limit state design. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Wind load Rzgar yk In case of earthquakeE0.

For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. Design compressive strength of concrete betonun hesap basn dayanm fctd: However, in the design of some structures like water tanks, tensile stress is limited for leak proofing.

Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. For instance, a slab which doesnt collapse but vibrates. 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? 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.

Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresBetonarme 1 Ders NotlarYrd. Murat Serdar KrlThis assumption is valid for service loads. Why do we need a probabilistic approach? 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 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. Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level.

Bernouilli-Navier hypothesis is valid. The probability distribution betlnarme them is usuallyassumed as normal gauss distribution.
