UT10, Steel Moment Resisting Frame with WUF-W Connections and Weak Panel Zone

Sungyeob Shin
Specimen UT10 was identical to Specimen UT08, except that it was subjected to column axial tensile loading. The specimen was applied increasing levels of column tensile loads and lateral cyclic loads at the top of the column simultaneously. The column axial loads of approximately 8 times the column lateral cyclic loads was force controlled and applied throughout the test. During the 6% story drift cycles, the maximum axial tension force of 1115 kips was applied...

10% EPS Geofoam Inclusion

Kimberly Lamote, Adda Athanasopoulos-Zekkos, Anthony Tessari & Inthuorn Sasanakul
This is a dynamic centrifuge test of a set of flexible retaining walls with sandy backfill. The objective of the test is to measure earth pressures and strains on the retaining walls, settlement of the backfill and accelerations throughout the model and then compare these results to another test where a layer of EPS has been added between the walls and the backfill. This will allow us to test the seismic isolation efficiency of EPS...

Real Time Hybrid Simlation Tests on Magneto-Rheological Damper at HIT

Ge(Gaby) Ou, Ali Ozdagli, Shirley Dyke & Bin Wu
This study conducted to investigate the performance of Robust Integrated Actuator Control Strategy (RIAC) developed by Ge Ou. With this objective in mind, a RTHS framework is developed at Structural Engineering Laboratory located at HIT. MR damper is tested as the physical substructure where as three story structure is modeled as the number substructure. Later, the shake table tests will be compared to corresponding RTHS using RIAC at IISL at Purdue University.

Direct in-situ soil liquefaction testing

Julia Roberts & Kenneth H. Stokoe
The objective of this testing procedure is to evaluate the earthquake-induced liquefaction susceptibility of an in-situ soil deposit. This is accomplished by determining how much excess pore water pressure can be developed for given shear strain levels and number of cycles. This approach is ideal because it directly characterizes the behavior of soil during large strain cyclic loading conditions, which are the same conditions expected during an earthquake. The raw data for this project was...

Web Plate Test #3-18

David Webster
Cyclic test of one-sixth scale SPSW using 18 Ga A1008 web plate specimen inside pin-connected boundary frame.

Web Plate Test #2-22

David Webster
Cyclic test of one-sixth scale SPSW using 22 Ga A1008 web plate specimen inside pin-connected boundary frame with flexible VBEs and stiff HBEs. The experiment was designed to investigate the flexural demand on the VBEs and the orientation of web plate tensile stresses.

Phase 2: Island90Rocks - water depth h=0.9 m: Measurements of radial wave propagation, wave runup, landslide kinematics and deposit.

Brian McFall & Hermann Fritz
The landslide tsunami generator (LTG) was deployed in the conical island scenario with a water depth of 0.9 m. The conical island configuration consists of the LTG mounted to a conical section with a base diameter of 10 m and a slope of 1:2 (vertical:horizontal) or α = 27.1˚. Wave gauges were strategically placed in the basin along rays at various angles from the landslide source to describe the tsunami wave angular dependence. A hybrid...

Column Splice Specimen 24B: PJP Flange Welds with PJP Web Weld

Sean Shaw, Amit Kanvinde, Selim Gunay &
Specimen 24A joins a W24x370 & W24x279. Each flange has a single bevel PJP weld and the web has a singe bevel PJP weld.The test objectives are to determine whether PJP-welded column splices have sufficient toughness and strength to resist demand incumbent upon column splices in SMRF system in regions of high seismicity. The specimen was subjected to a cyclic loading protocol that was generated through assessment of splice demands determined from non-linear time history...

Berkeley - Special Moment Resisting Frame Post Yield Behavior

Brian Olson & Stephen Mahin
The purpose of this experiment was to look at post yield behavior of an seismically isolated structure. The test specimen is a 2-story, 2-bay steel Special Moment Resisting Frame (SMRF) mounted on Triple Pendulum System (TPS) friction bearings. The specimen is subjected to a suite of ground motions scaled to different service levels (50% in 50 years, 10% in 50 years, 2% in 50 years). Post yield behavior is compared with unyielded behavior. Following the...

University at Buffalo - Low Aspect Ratio Rectangular Reinforced Concrete Shear Wall - Specimen SW2

Bismarck Luna, Jonathan Rivera, Josh Rocks, Caglar Goksu, Scott Weinreber & Andrew Whittaker
Although low aspect ratio shear walls are widely used in buildings and safety-related nuclear structures, their hysteretic behavior, including peak strength and effective elastic stiffness, has not been adequately characterized to enable robust performance and risk assessment. The US National Science Foundation funded a Network for Earthquake Engineering Simulation (NEES) research project on shear walls of conventional and composite construction to better understand the seismic behavior of these widely used structural elements. A total of...

OSU: In-Air Test, Aluminum Box, Long, X = 26

Harrison Ko & Daniel Cox
In-air tests were performed on the 1:5 scale aluminum and acrylic shipping containers. The primary variables examined were the pullback distance, non-structural mass, load cell type, and contact location. These tests allow us to compare against the full scale in-air results of Lehigh University and to provide a basis for later hydrodynamic tests.
