Shaking Table Study of Single-Story Masonry Houses. Volume 1: Test Structures 1 and 2
This investigation sought to establish minimum reinforcement requirements for single - story masonry dwellings for Seismic Zone 2 conditions. The experimental program was planned to make the test conditions as close to field conditions as possible; full - scale components of masonry structures were constructed from commercially available masonry units and were tied together using a small but typical roofing system. The addition of concrete slabs to the roof structure provided a reasonable approximation of both the dead load per foot of load - bearing wall and the inertia load transferred to the inplane shear walls. Plan dimensions were scaled down to maintain realistic response conditions. The height of walls was kept at 8 feet, 8 inches. Four houses were tested; the results for the first two houses are presented in this volume of the report. A detailed description of the measured response of each test structure is provided, and a quantitative assessment of parameters affecting the response is presented. Individual sections are devoted to explanations of the materials used; test specimens, procedures, and instrumentation; the test facility; test results; and analysis of test results. Discussed are out - of - plane strength, shear strength, experimental force levels, performance of cracked unreinforced walls, performance of partially reinforced walls, and amplification of peak base acceleration. The tests show that partially reinforced walls demonstrate excellent behavior under all levels of base excitation applied during the tests. Tables, figures, graphs, footnotes, and 36 references are provided. A list of data channels and an explanation of transverse strength of unreinforced masonry walls are appended.
