Key words


§      Prestressing strands prEn10138-3 Grade 1860MPa, Breaking load fpk=173kN, Elastic limit Fp0.1=152kN

§      TTD78, prestressing P = 24 strands * 173 * 0.75 = 3114kN at centre of TT web.

§      TTSlab-Deck in Master/Slave surface coupling by Line Mesh coupling stiffness 1E10

§      Nonlinear analyse involving birth and death elements of TTSlab in phase1 and 2.



Shown below is automatic models creation in Lusas.
