Characteristic tensile strength of concrete Betonun karakteristik ekme dayanm fyk: Betonarme 1 Ders NotlarYrd. Deprem yk Earthquake Load In case of lateral earth pressureH6. Murat Serdar KrlNM www.
In case of failure it doesn’t represent the real behavior of the RC sections. Murat Serdar KrlWhy do we need a probabilistic approach? Load and strength are probabilistic variables. Characteristic yield strength of reinforcement steel eliin karakteristik akma dayanm fcd: Concrete – curve is the curve obtained from uniaxialcompression.
What is the probability of reaching a limit state? Design tensile strength of concrete Betonun hesap ekme dayanm fyd: Murat Serdar KrlThis assumption is valid for service loads. Post on Dec 12 views.
BETONARME – 1
Concrete does betonaeme take any tension, all tensile stresses are taken by reinforcement. Both steel and concrete are assumed to be linear elastic and Hooke Law is valid. Characteristic compressive strength of concrete Betonun karakteristik basn dayanm fctk: Reinforcement steel is elastoplastic.
This assumption may be valid for service loads iletme ykleri However; its not valid anymore in case of failure.
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. The probability distribution of them is usuallyassumed as normal gauss distribution.
Structures mustbe designed so that the probability of reaching a limit state is lowerthan prescribed level. Load and material factors arecalled partial safety factors.
Thats why, stresses can not becalculated with reasonable accuracy.

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 KrlProbability of reaching or exceeding a limit state of structural system elements is restricted in limit state design. Ntlar yield strength of reinforcement steel eliin hesap akma dayanm Limit state design Limit durumlara gre hesap Betonarme 1 Ders NotlarYrd. Bernouilli-Navier hypothesis is valid. However, in the design of some structures like water tanks, tensile stress is limited for leak proofing.
