Boundary Status Coefficients of Regulations
LRFD - YDKT provides more realistic construction security than ASD-GKT with more realistic loading combinations, thanks to the precise statistical studies performed in load estimation and determination of safety factors.
LFRD - YDKT and ASD-GKT create design rules using different limit states. Economical design is carried out due to the difference between elastic and plastic design rules.
TS EN 1993-1-1 has the same philosophy as LRFD-YDKT. At the same time, compared to LRDF-YDKT, it provides a design closer to real behavior with highly detailed section classification, load increase coefficients and safety coefficients.
Although the design procedure with TS EN 1993-1-1 is quite complex compared to other regulations, it provides less initiative to engineers, LRFD - YDKT produces more practical solutions.
