Development
further developments for program package STATRA
input and output on principle corresponding with STATRA-8 resp. STATRA-9
for STATRA-8:
- calculation and evaluation of influence functions
- general continuous elastic support conditions
- eigenvalues in statics and dynamics (Eigenfrequencies, linear and nonlinear bifurcation of balance)
- arbitrary slightly curved spatially acting bars, cables
- incrementally solution for system of differential equations
- geometric nonlinear statics of large displacements
- physically nonlinear statics (spatially acting reinforced concrete and prestressed concrete bar structures)
for STATRA-9:
- improved model for interaction M-N-Q
- external prestressing
- combining with probabilistic analysis according to FORM
- combining with fuzzy set analysis
