3D-NLFRAME - Version 1.0.0

Description

Three-Dimensional Non-Linear Frame (3D-NLFRAME) is a multi-scale computer program that combine non-linear frame analysis in the higher scale and sectional fiber-based model in the lower scale. At present, 3D-NLFRAME is written in MatLab. The fiber based model is discretized and computed in parallel using OPENMP via the MEX File in MatLab. The Output can be viewed using GID.

Created By:

  • Bambang Piscesa (ITS-Indonesia)
  • Mario M. Attard (UNSW-Australia)
  • Ali K. Samani (Federation Univ.-Australia)

  • 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.
