The Earthquake Engineering Online ArchiveDRAIN-2DX, DRAIN-3DX and DRAIN-building: base program design documentationPrakash, Vipul; Powell, Graham H. UCB/SEMM-1993/16, Dept. of Civil Engineering, University of California, Berkeley, 1993-12, 282 pages (500/C23/93/16) The computer program DRAIN-2D (Dynamic Response Analysis of Inelastic 2-Dimensional Structures) was first released in 1973, and has been a useful analysis tool for many years. The main advantage of the program is that it is both simple and effective. Its capabilities, however, are very limited. Two extended versions of the program have been developed over the years, namely DRAIN-2D2 by Golafshani in 1983 and DRAIN-2DX by Allahabadi in 1987. These versions added more powerful capabilities to the program, while retaining its essential simplicity. They were not released because time and resources were not available to debug them and make them robust enough for general use. Using DRAIN-2DX as a starting point, a family of three new computer programs has been developed in the present phase of the work. These programs are identified as DRAIN-2DX, DRAIN-3DX and DRAIN-BUILDING. DRAIN-2DX and DRAIN-3DX are for general two-dimensional and three-dimensional structures, respectively. DRAIN-BUILDING is specifically for 3D building structures. The programs are based on the same technology and have similar features, so that they are clearly members of a family. Although they are more complex than DRAIN-2D, they are simpler than other general purpose nonlinear analysis programs. They also provide a number of features that are important for nonlinear seismic analysis, yet are not provided by other programs.
