We are conducting structural experiments using a loading frame. The photo shows a static loading experiment of columns. Cyclic Loading using hydraulic jacks attached to the top, left and right of the specimen. We also have various LVDTs and load cells.

We have a 3D deformation analysis system "Aramis" manufactured by GOM in Germany. Aramis can measure the displacement, deformation and strain of an object without contact using digital imate correlation (DIC). The stereo camera buil into the system has high resolution and frame rate. Therefore, this DIC system can obtaine informations that cannnot be obtained with conventional sensors. 

We have a universal testing machine that can perform compression testing of concretes and tensile testing of steel. We also have a concrete compression testing sensor that measures strain in compression testing of concrete.

We are evaluationg the structural performance of members using the finite element method analysis profram "FINAL". FINAL imprements various constitutive laws of concrete and steel materials. In the analysis, the displacement, strain and stress data of the members, which are more than those obtained frome the structural experiment.

We are evaluating the seismic performance of buildings using the elasto-plastic analysis program "SNAP" for 3D frame models. "SNAP" can perform eigenvalue analysis of buildings, load increment analysis considering the elasto-plastic behavior of members, and time history response analysis considering various seismic waves.

We can monitor structures using the accelerometer "sonas X02 SUP-X-X2". This accelerometer is small and wireless, making it easy to transport and install. In addition, the acceleration resolution is 0.06μG and the measurement range is ±15G. Therefore, this accelerometer can observe a wide range of vibrations in buildings, from microtremor to strong motion.
