Reinforcement steel is elastoplastic.
Design compressive strength of concrete betonun hesap basn dayanm fctd: Betonarme 1 Ders NotlarYrd. Murat Serdar KrlThis assumption is valid for service loads. 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. What is the probability of reaching a limit state?
Load and strength are probabilistic variables. Murat Serdar KrlNM www. Live load Hareketli yk T: Bernouilli-Navier hypothesis is valid. Murat Serdar KrlWhy do we need a probabilistic approach? Both steel and concrete are assumed to be linear elastic and Hooke Law is valid.
Wind load Rzgar yk In case of earthquakeE0.

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. For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. Design tensile strength of concrete Betonun hesap ekme dayanm fyd: 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. Murat Serdar KrlProbability of reaching or exceeding a limit state of structural system elements is restricted in limit state design.
Concrete – curve is the curve obtained from uniaxialcompression. Why do we need a probabilistic approach? Limit betoname design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresBetonarme 1 Ders Dsrs.
This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.
Limit state design Limit durumlara gre hesap Fundamental principles and derw for design of reinforced concrete structuresMain assumptions of this methodBetonarme 1 Ders NotlarYrd. Post on Dec 12 views. Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level.
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 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.
Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Deprem yk Earthquake Load In case of lateral earth pressureH6.
Murat Betonarke KrlIts not a realistic assumption since concrete has not a constant elastic modulus. For instance, a slab which doesnt collapse but vibrates.
The little tensile strength of concrete is neglected. Home Documents Betonarme 1 Ders2 Ing.

Concrete does not take any tension, all tensile stresses are taken by reinforcement. Murat Serdar KrlThe probability of collapse is assumed to reduce to predetermined value by increasing characteristic loads betonarmee load factors f anddecreasing the characteristic strength with material factors m.
Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: The probability distribution of them is usuallyassumed as normal gauss distribution. Characteristic vers strength of reinforcement steel eliin karakteristik akma dayanm fcd: In case of failure it doesn’t represent the real behavior of the RC sections.
