Tests necessary for liquefaction analysis and seismic response analysis! Relatively faithful reproduction of stress and deformation conditions in the original ground.
To conduct seismic design of structures rationally, it is necessary to accurately understand the properties of the ground directly beneath the foundation and the surrounding soil. The ground failure phenomena that often occur during major earthquakes are significant factors that greatly affect the seismic resistance of the superstructure. The "hollow torsional shear test" applies torque to the upper end of a hollow cylindrical specimen, twisting it in the circumferential direction to induce shear deformation throughout the specimen. Compared to indirect shear tests, it has the advantage of being able to relatively faithfully reproduce the stress and deformation conditions of the original ground. 【Types of tests that can be conducted】 ■ Torsional shear test ■ Repeated torsional shear strength test (liquefaction characteristics) ■ Repeated tests to determine deformation characteristics *For more details, please refer to the PDF materials or feel free to contact us.
