Seismic Finite Element Analysis of Masonry Buildings Reinforced with Ferrocement

  • P. Ballesteros
  • P. R. Reyes

Summary

The structural analysis by Finite Element Method, assembling the beam and plate elements, of six degrees of freedom per each nodal point is discussed. The rotational stiffness Kez is obtained and the aplication, to the analysis and design of a masonry building, which has been subjected to earthquake damage in its load bearing walls, is also presented.
