Murat Serdar KrlIts not a realistic assumption since concrete has not a constant elastic modulus. The little tensile strength of concrete is neglected. Design compressive strength of concrete betonun betomarme basn dayanm fctd: What is the probability of reaching a limit state? For instance, a slab which doesnt collapse but vibrates. Murat Serdar KrlNM www.
Bernouilli-Navier hypothesis is valid. Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level. Design tensile strength of concrete Betonun hesap ekme dayanm fyd: Design yield strength of reinforcement steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd.
For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. 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.
Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Thats why, stresses can not becalculated with reasonable accuracy.

Post on Dec 12 views. Concrete – curve is the curve obtained from uniaxialcompression. The first stage of design making design of a betonarmr for theultimate limit state and the following step is checking the serviceabilityrequirements deformations and cracks.
Why do we need a probabilistic approach? Home Documents Betonarme 1 Ders2 Ing. However, in the design of some structures like water tanks, tensile stress is limited for leak proofing.

Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Reinforcement steel is elastoplastic. Murat Serdar KrlThis assumption is valid for service loads. Wind load Rzgar yk In case betonarmd earthquakeE0. Murat Serdar KrlLimit state design Limit durumlara gre hesap Limit state des a particular state of a structure which may becollapse or loss of function, either partial or total.
The probability distribution brtonarme them is usuallyassumed as normal gauss distribution. Murat Serdar KrlWhy do we need a probabilistic approach? Betonarme 1 Ders NotlarYrd. 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 KrlProbability 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 11 real behavior of the RC sections. Load and strength are probabilistic variables. Live load Hareketli yk T: Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. Concrete does not take any tension, all tensile ontlar are taken by reinforcement.
Deprem yk Earthquake Load In case of lateral earth pressureH6. Load and material factors arecalled partial safety factors.
Probability of reaching or exceeding a limit state of structural system elements is restricted in limit state design. Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach. Betobarme assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.
