  • STUDY ON TENSILE PERFORMANCE OF COLUMN-TO-BEAM CONNECTION WITH SAO-SHACHI JOINT FOR TRADITIONAL WOODEN BUILDINGS

    URAKUBO Mikiya, MIYAMOTO Mitsuhiro, UTSUNOMIYA Naoki, NAKAO Masato, OHASHI Yoshimitsu

    <p>Column-to-beam connections are important to evaluate the seismic performance of traditional wooden buildings accurately. However, there are many types of traditional joints. Some of them have not been studied for evaluating their seismic performance, such that almost no experimental data and no evaluation methods are available. This study aims to evaluate the tensile performance of column-to-beam connections with Sao-shachi joint based on the full-scale tests. It is shown that the evaluation formula for the column-to-beam connections with Yatoi-sao-shachi joint in the past is applicable to evaluate the tensile performance of these connections.</p>

  • ESTIMATION ACCURACY OF RESTORING FORCE CHARACTERISTICS OF TENSILE BRACE SHEAR WALL WITH HIGH-PERFORMANCE BRACE CONNECTOR BY STATIC INCREMENTAL ANALYSIS

    NAKAO Masato, FURUTA Tomoki

    Language:Japanese   Publishing type:Research paper (scientific journal)   Publisher:Architectural Institute of Japan   Joint Work  

    <p>To develop a new brace connector, static incremental analysis of a braced shear wall with a detailed analysis model was conducted. Several kinds of load-displacement relationships, that are necessary for the analysis model, were defined based on elemental tests, such as tensile tests and shear tests of the screws. The shear stiffness of the tensile brace shear wall from the analysis was higher than the one from a shear loading test, while the maximum shear strength from the analysis with the column and the brace of high density was near the one from the shear loading test.</p>

  • EFFECT OF BRACE CONNECTOR SHAPE ON SEISMIC PERFORMANCE OF TENSILE BRACE SHEAR WALL

    <p>To clarify the difference in the structural performance of the plate-type-connector, the box-type-connector, and the L-shaped-connector, the static shear loading tests of tensile brace shear walls were performed. From the tests, it was found that the plate-type-connector provides high lateral stiffness, while the structural performance of the L-shaped-connector was lower than the ones of the plate-type-connector and the box-type-connector. Regarding the relationship between the axial load of a brace and the diagonal displacement of a wood frame, the difference in initial stiffness was not detected in the specimens with 1P, 1.5P, and 2P of wall length.</p>
