Housed in a completely remodeled and air conditioned room in the Civil Engineering Department, this state-of-the-art engineering computing facility was developed with funds from Puerto Rico EPSCoR, the Puerto Rico Legislature, the National Science Foundation, and the Civil Engineering Department. The ACF exists to support all CIRC researchers and graduate students. In the structures area, CIRC faculty and students have developed outstanding PC-based programs for structural analysis and design that feature easy-to-use interactive graphical interfaces.
