Structural Analysis with Dynamic Loads using Direct Integration
ROHR2STOSS is an alternative dynamic module in the program system ROHR2. The results of ROHR2STOSS are integrated into the ROHR2 processing.
ROHR2stoss is an alternative dynamic module in the program system ROHR2. The results of ROHR2stoss are inte-grated into the ROHR2 processing. The task of the program ROHR2stoss is the assessment of temporal varying load such as those induced by fluid hammer in pipe structures using the direct integration method of the differential equation. Linear as well as non-linear boundary conditions are considered.
For linear boundary conditions, this method is an alternative to the modal time history calculation of the ROHR2 standard calculation process. The possibility to include non-linear elements allows the design of new elements, which cannot be analyzed by modal time history calculation:
Support with gap
Shock absorbers with activation limits
Geometric non-linearity of angulating supports
Constant supports with friction
Supports and springs with hysteresis
Visco-Dampers with resistance proportional to velocity
Springs with dampers
Soil damping
Friction supports, with or without guides
Expansion joints with friction
Shock
Analysis of impacts between pipes.
ROHR2 Integration
ROHR2stoss is integrated into the ROHR2 environment. This makes it easy to switch between modal time-History analysis and Direct-Integration in Dynamic fluid Hammer load cases.

ROHR2fun - ROHR2stoss function analysis
ROHR2stoss includes the program ROHR2fun. ROHR2fun is used for graphical representation and analysis of functions, esp. load inputs and results of ROHR2stoss.
