Previous researches have pointed out that the near-fault seismic wave produces a significant velocity pulse and permanent displacement on the ground. The current seismic design specification has not yet been fully considered this effect comprehensively. National Center for Research on Earthquake Engineering (NCREE) has built up a second experimental center in Tainan. One of the key features of this center is the test facility called "High-performance 6-DOF shaking table", that is capable of simulating near-fault ground motion for large-scale specimens. This study intends to design a versatile steel frame to verify the capacities of the shaking table. The versatile steel frame, designed with two span in each direction and two story, provides flexibility to be assembled with different shape in plan (L-, or Rectangular shape), braces, and damping. Through the input of a series of acceleration record, the precision of the movement and acceleration of the shaking table, as well as the response of the frame can be measured. Test results from the specimen is then analyzed by PISA 3D, a software developed by NCREE (National Center for Research of Earthquake Engineering). The experimental results show that the accuracy of the vibration table reaches its design goal and meets the experimental requirements. The acceleration and displacement response of the versatile steel frame are similar to the analytical results, and the dynamic response period is similar to the analysis model. The analytical model can be used for the future study. Also, analytical results indicate that the frame damping ratio appears to be overestimated by the available estimated method. Future study is needed in this area. Min-Yuan Cheng 鄭敏元 2017 學位論文 ; thesis 122 zh-TW |

碩士 === 國立臺灣科技大學 === 營建工程系 === 105 === Taiwan is located on a region where the Philippine plate and the Eurasian plate intersect, and as a result, seismic activity occurs frequently. Previous researches have pointed out that the near-fault seismic wave produces a significant velocity pulse and permanent displacement on the ground. The current seismic design specification has not yet been fully considered this effect comprehensively.
National Center for Research on Earthquake Engineering (NCREE) has built up a second experimental center in Tainan. One of the key features of this center is the test facility called "High-performance 6-DOF shaking table", that is capable of simulating near-fault ground motion for large-scale specimens. This study intends to design a versatile steel frame to verify the capacities of the shaking table.
The versatile steel frame, designed with two span in each direction and two story, provides flexibility to be assembled with different shape in plan (L-, or Rectangular shape), braces, and damping. Through the input of a series of acceleration record, the precision of the movement and acceleration of the shaking table, as well as the response of the frame can be measured. Test results from the specimen is then analyzed by PISA 3D, a software developed by NCREE (National Center for Research of Earthquake Engineering).
The experimental results show that the accuracy of the vibration table reaches its design goal and meets the experimental requirements. The acceleration and displacement response of the versatile steel frame are similar to the analytical results, and the dynamic response period is similar to the analysis model. The analytical model can be used for the future study. Also, analytical results indicate that the frame damping ratio appears to be overestimated by the available estimated method. Future study is needed in this area.
