Shaking Table Test Of Frame - Packed Wall Frame With Assembled Straw

Infilled flame is a very common structural system used in the building structures, which isoften used brick wall, brick or other masonry materials separated or external enclosure. Butframes in traditional designs consider the infilled wall as the non-structural component, theyignore their effect on the seismic performance of main structure and can’t truthfully reflect. Themain cause is that infilled walls can collaborate with flame beams and columns together toundertake the seismic action, which can affect the mechanical performance of the framestructure．Wenchuan earthquake survey found that infill walls infilled frames structure damage isthe most serious. Thus, finding a lightweight, environmentally wall instead of ordinary infilledwalls as a matter of urgency.Fabricated straw wall is a new type of building walls that is our group proposed, which ischaracterized by a sandwich-type structure with tenon and groove wall assembly, and does notrequire any additional connections. Noise insulation performance is well of this wall. Fabricatedstraw wall is a lightweight, environmentally wall.This paper presented a shaking table test of1/3scale model of the frame structure buildingbuilt with fabricated straw walls. In the test, the test process was recorded, and the data ofacceleration responses, displacement responses and strain responses was collected. Besides, thewhite noise was used to survey the frequency shift under different earthquake levels. Throughanalyzing the testing data, the variation of dynamic characteristics and the seismic responses ofthe model were studied. Then, according to the analogical ratio between the scale model and theprototype, the dynamic characteristics and the seismic responses of the prototype were calculated.The following are the lists of main conclusions：(1) The model performed elastically and had no visual damage for frequently earthquake ofintensity VII(2) The model structure natural frequency sharp decline under rarely occurred earthquake ofintensity VII VIII IX, which enter into the non-linear stage.(3) The specimen was still not collapse in the order of1983gal PGA.(4) The damping ratios of model structure was26.62%, which showed that model structurehad strong reduced seismic energy(5) The maximum inter-story drift ratios of the prototype under rarely occurred earthquakeof intensity VIII was1/796and the maximum inter-story was6.74mm, respectively.These all indicated that the prototype can satisfy the seismic criteria under differentearthquake levels.
