Comparison of shaking table results of a self-centering bridge bent with finite element simulations juan meriles fall 2019A brief study of machine learning and deep learning applications xulai xu fall 2019experimental seismic evaluation of reinforced concrete box-girder bridge systems svetlana khaykina spring 2000.

Abstract a series of shaking table tests were conducted on scaled utility tunnel models with and without construction joints under non-uniform input earthquake wave excitationDetails of experimental setup are first presented with particular focuses on: design and fabrication of double-axis laminar shear box with a rectangular hole opened on its side walls; design of two devices for measuring.

Apr 04 2016 shaking table performance of a new bridge system with pretensioned rocking columnsA new bridge bent system has been developed to reduce on-site construction time minimize residual displacements even after a large earthquake and reduce seismic damage in comparison with conventional cast-in-place construction.

Behavior is to conduct shaking table tests under a centrifugal field using a model specified from the actual structure in accordance with the similarity law so as to allow economic evaluation of alternative designs investigation of complex problem areas and validation of numerical methods with instrumented physical models.

Nov 05 2020 experimental vibration analysis for civil structures: testing sensing monitoring and control covers a wide range of topics in the areas of vibration testing instrumentation and analysis of civil engineering and critical infrastructureIt explains how recent research development and applications in experimental vibration analysis of civil engineering structures have progressed.

Shaking table is important experimental equipment to carry out antiseismic researchResearch conclusion comparison and analysis concerning the developmental history constructional situation performance index control algorithm and experimental technique of the internal shaking table were reviewed and comparedSuch functional parameters as internal shaking tableamp;x2019;s table-board.

Shaking table system for geotechnical centrifuge.

Shaking table tests of six innovative types of large-scale bridge models as well as relevant conclusions from both experimental and initial analytical studies.

Shaking table tests on bridge structures and bridge piers information is rather scarce and just a few results are found in literatureThe tests performed at lnec carvalho et al 1978 at the university of california williams and godden 1976 and at ismes facilities casirati et al 1996 are among the few papers published on the subject.

Specific to severe damage to curved bridges in earthquakes caused by the excessive force of the fixed bearings and piers a new seismic design method on curved bridges considering bearing friction sliding isolation is proposed in this paperSeismic model bridge and isolation model bridge with similarity ratio of 120 were made and the shaking table comparison test was conducted.

The ability to gauge how all the parts of a building perform together as an integrated whole rather than as individual components is another major advantage offered by large shake tablesBased on shaking tests of individual walls and other parts against the kind of lateral loads that might develop in an earthquake the cold-formed.

Initial validation of mobile.

The observed dynamic characteristics of the bridge with the behavior of its structural el-ementsData collected from an instrumented large-scale bridge specimen during shaking table tests are also analyzed to gain insight about the response of the bridge bents dur-ing the earthquakes and propose a strategy to model their seismic behavior.

Therefore the objective of the present study was to test two-column bridge bents dynamically by subjecting them to actual time earthquakesThree models with columns aspect ratios of 63 were designed according to the updated caltrans design criteria.

These responses with the seismic demands of the test buildingShake table test program the test building consisted of a cast-in-place five-story reinforced concrete structure with moment-resisting frames providing lateral resistance in the direction of shaking east-west direction figure2a.

Experimental vibration analysis for civil structures.

Vibrations induced from the shake table before each model testThe computed shear wave velocity of sand ranged from looms to 150 ms before and after shakingThe shaking table tests were conducted in march 1999.

pushover analysis and seismic response of uhpc two-column bridge bent 2nd intSymposium on ultra-high performance concrete june 2-4 2019 albany ny2017 pretest analysis of a shake table test of a two-span steel girder bridge incorporating abc connections proceedings of 2017 national abc conference.

• the results of the shaking table tests are in very good qualitative agreement with previously published anastasopoulos et al2012 experimental results from monotonic and slow-cyclic pushover testsIn quantitative terms the differences are non-negligible with the shaking table tests yielding much larger settlement for all cases examined.
