Seismic performance of timber frames
Pospíšil, Stanislav ; Urushadze, Shota ; Koleš, Jan
A series of dynamic experiments was performed on one-story timber frame. In comparison with the previous frames [1, 2], improved connection between column and girder was used here. The tests included sinusoidal sweeps in two directions, arbitrary signals simulation earthquake loads in three directions, and snapback tests. Various parameters were measured, for example tension on columns and slabs, rotation between columns and beams, displacement of columns and acceleration of columns and beams. All these parameters lead to classification of the frame behavior with designed type of connection, for example the natural frequencies, eigenmodes and other dynamical properties of the structure. Parameter description will allow us to design and improve mathematical model of the timber frame.
