Murat Serdar KrlLimit state design Limit durumlara gre hesap Limit state defines a particular state of cers structure which may becollapse or loss of function, either partial or total. Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresMain assumptions of this methodBetonarme 1 Ders NotlarYrd.
Design tensile strength of concrete Betonun hesap ekme dayanm fyd: 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.
Home Documents Betonarme 1 Ders2 Ing. However, in the design of some structures like water tanks, tensile stress is limited for leak proofing. Why do we need a probabilistic approach? Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety not,ar structures by using a probabilisticapproach.

Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: In case of betonamre it doesn’t represent the real behavior of the RC sections. 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. Live load Hareketli yk T: 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 hesap basn dayanm fctd: Wind load Rzgar yk In case of earthquakeE0.
Load and material factors arecalled partial safety factors. Murat Serdar KrlNM www.
Deprem yk Earthquake Load In case of lateral earth pressureH6. Limit state design Limit durumlara gre hesap Fundamental principles and methods for design of reinforced concrete structuresBetonarme 1 Ders Derrs. For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. What is the probability of reaching a limit state? Thats why, stresses can not becalculated with reasonable 11. Both steel and concrete are assumed to be linear elastic and Hooke Law is valid.

The probability distribution of them is usuallyassumed as normal gauss distribution. For instance, a slab which doesnt collapse but vibrates.
Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level. Murat Serdar KrlThis assumption is valid for service loads. Load and strength are probabilistic variables. 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. Characteristic yield strength of vers steel eliin karakteristik akma dayanm fcd: Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Murat Serdar KrlWhy do we need a probabilistic approach?

Concrete – curve is the curve obtained from uniaxialcompression. Bernouilli-Navier hypothesis is valid. Reinforcement steel is elastoplastic.
