Program: FLUSH Title: Seismic Soil-Structure Interaction Analysis Developer: J. Lysmer, Department of Civil Engineering, University of California, Berkeley 1975 Modified: N. Deng, San Francisco 1991 Category: Geotechnical Platform: CDC mainframe, NOS, FTN4, single precision IBM mainframe, VM/CMS, Fort4H, Lahey Fortran F77L Reference: Lysmer, J., T. Udaka, C.F. Tsai, and H.B. Seed, "FLUSH-- A Computer Program for Approximate 3-D Analysis of Soil-Structure Interaction Problems," Earthquake Engineering Research Center, Report No. UCB/EERC-75/30, University of California, Berkeley, November 1975. Summary: The computer program FLUSH is a further development of the complex response finite element program LUSH (Lysmer et al., 1974). The new program is considerably faster than LUSH and it includes a large number of new features which make the program more efficient and versatile. The program is now in its sixth version and provides a complete tool for seismic soil-structure interaction analysis by complex response method. The FLUSH program includes the following features: 1.Plane strain quadrilateral elements for modeling of soils and structures. 2.Beam elements for modelling of structures. 3.Multiple nonlinear soil properties for equivalent linear analysis. This allows for different damping in each element. 4.An approximate 3-D ability which makes it possible to perform certain structure-soil-structure interaction analyses at essentially the same cost as 2-D analysis. 5.Transmitting boundaries which greatly reduce the number of elements required and eliminates the need to perform several analyses to ensure that the finite element boundaries are placed far enough away from the structures. 6.A new out-of-core equation solver which reduces core-size problems. 7.Internal deconvolution. This feature eliminates the need to perform an independent site response analysis for determination of the rigid base motions. 8.Convenient file handling features which provide restart ability and a permanent record for later recovery of details of the solution. 9.Printed, plotted or stored output time histories of acceleration and bending moments. 10.Computation of maximum shear forces in beam elements. 11.Printed or stored acceleration velocity response spectra. 12.Plotting of Fourier amplification functions. 13.Optional baseline correction of input and output motions. 14.Several additional features which improve the efficiency, utility and clarity of the program (Optional RMS method for strain computations, new interpolation scheme, etc.).
