Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level. Home Documents Betonarme 1 Ders2 Ing. 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.
Murat Serdar KrlProbability of reaching or exceeding a limit state of structural system elements is restricted in limit state design.
Betonarme 1 Ders2 Ing – [PDF Document]
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 structuresBetonarme 1 Ders NotlarYrd. Murat Serdar KrlLimit state design Limit durumlara gre hesap Limit state defines a particular state of a structure which may becollapse not,ar loss of function, either partial or total.
Betonarme 1 Ders2 Ing
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. Load and material factors arecalled partial safety factors.
Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: 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. Concrete does not take any tension, all tensile stresses are taken by reinforcement. Live load Betonarrme yk T: The little tensile strength of concrete is neglected. This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.
Murat Serdar KrlIts not a realistic assumption since concrete has not a constant elastic modulus. For instance, a slab which doesnt collapse but vibrates. In case of failure it doesn’t represent the real behavior betonzrme the RC sections. What is the probability of reaching a limit state? 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 KrlNM www. Murat Serdar KrlWhy do we need a probabilistic approach? Probability of reaching or exceeding a limit state of structural system elements is restricted in limit state design.
Wind load Rzgar yk In case of earthquakeE0. Load and strength are probabilistic variables.
Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. Post on Dec 12 views. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: For instance, underthe effect of a strong ground motion, the assumption of materiallinearity is not valid. Design yield strength of notlqr steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd.
The probability distribution of them is usuallyassumed as normal gauss distribution. Bernouilli-Navier hypothesis is valid.
Deprem yk Earthquake Load In case of lateral earth pressureH6. Reinforcement steel is elastoplastic. Betonarme 1 Ders NotlarYrd. Concrete – curve is the curve obtained from uniaxialcompression.
Murat Serdar KrlWe need to know probability distribution of load and strength aswe can determine the safety of structures by using a probabilisticapproach. Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Thats why, stresses can not becalculated with reasonable accuracy.
