The purpose of this thesis is to investigate the proper
installation location of strong motion seismometers for
various structure systems. The procedure includes following
main steps: Step 1 : determining the natural frequencies
and their corresponding modal shapes Step 2 : determining
the major contribution modes to the earthquake response in
X direction and Y direction Step 3 : deciding the proper
location on horizontal plane Step 3 : deciding the proper
location on vertical plane In step 2, 3, 4 the 1940 El
Centro earthquake is used to calculated the earthquake
response. According to the analysis executed, it is concluded
that: 1. For complicated structure system, the influence of
tortional mode will be more visible. 2. For structure system
with L-shape plane, the long wing will influence the channel
parallel to the short wing. 3. Non-symmetrical Wall system
has visible influence on the location of seismometers,
specially on the channel parallel to the wall plane. 4. The
influence due to the flexure rigitity of slab and the
strong-stiffness-story are not very visible in the cases
investigated. 5. In Ming-Li Elementary School Building and the
Administration Building of Cheng-Kung University, some of the
seismometers installed need to be adjusted.
