Shaking Table Study of Single-Story Masonry Houses. Volume 2: Test Structures 3 and 4

摘要

Methodology and results are reported from an experimental investigation aimed at determining reinforcement requirements for single - story masonry dwellings in Uniform Building Code Seismic Zone 2 under realistic seismic conditions for that zone. The overall study tested four masonry houses; this volume reports results from the testing of two of the houses. One house was constructed from two - core hollow clay brick units with nominal dimensions of 6 x 4 x 12 inches, and the other was made of standard hollow concrete blocks with nominal dimensions of 6 x 4 x 16 inches. All of the test houses had both unreinforced and partially reinforced wall panels, assembled to form 16 - feet square models of typical masonry houses. Masonry units used in the construction of all test structures were full - sized units. Each house was provided with a timber truss roof structure to which weights were attached so as to obtain realistic loads on the bearing walls. Methods, models, and test facilities used in the study are described. A detailed description of the measured response of each test structure is provided, and a quantitative assessment of parameters affecting the response is presented. The tests show that partially reinforced walls demonstrate excellent behavior under all levels of base excitation applied during the tests. Tables and 10 references are provided, and a list of data channels is appended. Diagrams and graphs are included. (Author abstract modified).
