Characteristic compressive strength of nottlar Betonun karakteristik basn dayanm fctk: For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. 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.
Thats why, stresses can not becalculated with reasonable accuracy. Concrete – curve is the curve obtained from uniaxialcompression.
The little tensile strength of concrete is neglected. Live load Hareketli yk T: Load and strength are probabilistic variables.

Post on Dec 12 views. In case of failure it doesn’t represent the real behavior of the RC derrs. What is the probability of reaching a limit state? However, in the design of some structures like water tanks, tensile stress is limited for leak proofing.
Load and material factors arecalled partial safety factors. Reinforcement steel is elastoplastic. Murat Serdar KrlNM www. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Murat Serdar Nltlar 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 KrlIts not a realistic assumption since concrete has not a constant elastic modulus. Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level.
Why do we need a probabilistic approach? Wind load Rzgar yk In case of earthquakeE0. Limit state design Limit durumlara gre beotnarme Fundamental principles and methods for design of reinforced concrete structuresBetonarme 1 Ders NotlarYrd.
Both dders and concrete are assumed to be linear elastic and Hooke Law is valid. 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: Probability of reaching or exceeding a betonarmw state of structural system elements is restricted in limit state design. Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Murat Serdar KrlWhy do we need a probabilistic approach? 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.

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 nolar m. The probability distribution of them is usuallyassumed as normal gauss distribution. Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach. Bernouilli-Navier hypothesis is valid.

For betonar,e, a slab which doesnt collapse but vibrates. This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.
Murat Serdar KrlThis assumption is valid for service loads. Concrete does not take any tension, all tensile stresses are taken by reinforcement.
