I use both RISA 3D and MIDASGEN and highly recommend both. RISA is the ultimate in user friendliness for general structural analysis and design although Report outputs/presentation could be improved. For more refined structural analysis such as time history MIDASGEN is also excellent. Learning curve is a bit longer than for RISA but understandable considering its capabilities but again as for RISA modelling is a dream. Like RISA, MidasGEN could improve the presentation of the results.
