This package of NBSD-Software tools are provided for reducing seismic vulnerability of existing or new Reinforced Concrete low rise buildings in Seismic Regions, and is provided at a reduced price to make it accessible to the affected regions, using Metric (MPa or Mks – Kgf/cm2) Units.

These (5) software tools are meant for design professionals to provide quick and reliable analysis and design of simple buildings in the region having concrete floors, which can be repaired with suitable new RC Shear Walls with new RC spread footings. Simple RC building structures retrofitted for EQ loads in highly seismic regions will be adequate for hurricane loads, as long as cladding (i.e Plywood) is used at building openings to protect against wind borne projectiles.
