Abstract: An investigation is made of a potential retrofit system for in-fill masonry walls subjected to blast effects that consist of geotextile or geogrid materials anchored to the roof, floor slabs and beams of conventional structures. Fourteen static tests on geotextile and geogrid materials were conducted to provide an initial evaluation of the performance of the retrofit systems. The ultimate capacity and load-deflection behavior of these retrofit systems, including connections, were determined. The static tests were conducted by slowly increasing the uniform load (water pressure) in a 6-ft-diam static chamber. The tensile strength of the materials used in the experiments varied from 575 lb/in. to 2,900 lb/in. Test loading pressures and structural response deflections were recorded. Resistance functions were developed from the experimental data for use in making dynamic response calculations. It was concluded from the experiments that the primary parameters affecting the capacity of the retrofit system were the material tensile strength, machine/cross-machine direction, and the anchoring system (bolt size and spacing).
