Two reaction walls for lateral loading and steel frames for vertical loading

This laboratory experimentally investigates the seismic safety of building structures using a full-scale test building. The test structure installed in the laboratory is constructed with the reaction floors,(floor A 20m(width)x25m(length); floor B 15mx20m) together with two 25m-high reaction walls crossed at right angles by another 15.5m-high wall. A full-scale seven-story bui1ding with a maximum floor area of 400m can be tested. The horizontal loading to a test building is carried out using actuators which are attached to the reaction wall. Since these actuators are accurately controlled by a computer, the test building is forced to move just as an actual building moves when subjected to a real earthquake monition. Through this test method named as pseudo-dynamic test, the dynamic behavior of a building during an earthquake can be investigated quite in detail.
