ASTEA MACSロゴASTEA MACS画像

Nonlinear thermal stress Analysis Program
ASTEA MACS (ASTEA-MAss Concrete Structure analysis system) is a FEM system for the simulation of transient thermal conduction and stress analysis for concrete structures, which takes account of the history of heat generation during construction, the temperature-dependency and time-dependency of material properties, the addition of elements and variation of boundary conditions due to concrete Casting, and the occurrence of crack.

ASTEA-MACS is featured with following facilities:
a) easy-to-use user interface based on Window-system
b) on-line help capability for menu operation and data building
c) easy definition of the changes of boundary and constraint conditions during concreting
d) incorporated standard database of concrete properties
e) analyses for both thermal conduction and thermal stress
f) consideration of nonlinearties such as heat generation properties and mechanical properties due to hydration.

ASTEA-MACS pre-processing facilities include
Semi Automatic mesh generation
Check for the generated mesh
Boundary condition specification for each lift
Automatic recognizition of boundary variation due to the lift change.
Reference of property database

ASTEA-MACS post-processing facilities include the graphic representation and print of:
deformation
contour
crack
distribution of specified section
time-history
principal stresses

ASTEA-MACS property database facilities include:
JSCE RC standard:JCI proposed data
Modification and addition of property database for up to 19 items such as conductivity, specific heat, Young's modulus, compressive strength.

ASTEA-MACS transient thermal conduction analysis abilities include:
Analysis for boundaries of adiabatic, convection,radiation and prescribed temperature
Consideration of time-dependency for convective heat transfer coefficient, environmental temperature and radiating temperature
Element heat generation taken as the function of time
Choice of time integral method from, forward-Euler, backward-Euler,or crank-Nicholson method.
User subroutions corresponding to various problems
Output files for both node-temperature and accumulated temperature

ASTEA-MACS nonlinear thermal-stress analysis facilities include:
Consideration of time-dependency for Young's modulus, Compressive and tensile strength
Analyses for tensile collapse, compressive yielding and creep
Special problem through user defined subroutines
Gravity loading can be considered
Steel bar can be set in four directions at most
Time step for stress analysis can be flexibly set in terms of the time step for thermal analysis.
