- Abstract
- The report describes recent experimental results on the dynamic behavior of a one story steel structure tested with fixed, semi-rigid, and flexible connections. The structure was subjected to various intensities of three historical earthquake acceleration time histories by means of the shaking table at the Earthquake Engineering Research Center at the University of California, Berkeley. The details of the structure are presented together with the instrumentation programs; the extent of the data collected in the tests is described. In addition, to the dynamic properties of the structure, moment-rotation, shear-rotation, and several other response parameters of the three different connections are presented. The global responses of the structure with the three different connections under three types of excitations are examined. The behavior of flexible and semi-rigid structures under dynamic loading is studied, and their respective responses are compared to that of the fixed structure subjected to similar earthquakes. The use of flexible and semi-rigid structures in low to moderate earthquake zones is investigated and commented on.
