Program Features:
- Parallel computing using OPENMP in MatLab.
- Support empirical constitutive model such as: Mander [1], Attard and Setunge [2], and Samani and Attard [3].
Future Development:
- The code will be complete migrated to VC#.Net and the heteregenous computing is employed to massively speed up the computation.
- Inter-connecting with ITS-RCCAD program will be deployed in the future using Windows Communication Foundation (WCF). Hence, 3D-NLFRAME will only focus on the development of the upper scale (Frame Analysis)
while ITS-RCCAD focus on the lower scale (Sectional Analysis).
- Samani and Attard [4] concrete Lateral strain model will be added to nullified the requirement to compute the effective confinement presure when the ties is yielding.
