概要: This paper proposes new masonry walls using ductile interlocking blocks for retrofitting existing buildings. The presented walls are capable of resisting out-of-plane loads by the interlocking mechanism between blocks. Three 3/10 scale reinforced concrete frames were prepared, and two of them were retrofitted by the walls. Quasi-static loading tests of the specimens were carried out in the in-plane and out-of-plane directions, to compare their seismic performance. Installing the block walls, the strength of retrofitted specimens increased but ductility decreased. Moreover, one of them not only supported axial loads but also exhibited a frictional lateral resistance after failure of the columns. 続きを見る

概要: Objectives of this study were to propose evaluating method of axial load carrying capacities of R/C columns after shear failure using experimental data reported in the previous paper. For this purpose two criteria were examined, i.e. Mohr-Coulomb criterion and slip criterion between shear crack surfaces considering friction. Effects of confinement given by various hoop reinforcing details were specially paid attention. Two assumptions were used, i.e. i)the cohesive stress was degraded due to damage of core concrete and ii)confining stress by hoop reinforcement was degraded due to damage of reinforcement depending on the details. Finally evaluating equations of maximum deflection angles of shear failing columns experienced before losing their axial load carrying capacities were propose according to two assumptions mentioned above. 続きを見る

概要: Objectives of this study were to examine axial load carrying capacities of R/C columns after shear failure. For this purpose static loading tests of R/C columns were conducted. Confinement of hoop reinforcement to core concrete was one of the most important effects to be discussed so different hoop reinforcement details were studied, i.e. welded hoop for good confinement type, hoop with 135 deg hook for normal confinement type and hoop with 90 deg hook for poor confinement. Using these specimens centrical axial loading test to examine the basic confining effects and lateral loading test under constant axial load to examine the axial load carrying capacity were conducted. 続きを見る

概要: This paper mainly discusses seismic performances of specially designed unreinforced masonry (URM) structures. Firstly, lateral force resisting mechanisms of masonry in filled frames were introduced through test results of concrete block in filled reinforced concrete frames with and without a door opening. Based on major findings from the tests, a method to enhance seismic performances of URM structures using interlocking masonry units was proposed. Two new URM walls consisting of brittle and ductile interlocking masonry units were tested and their performances were compared with that of a conventional one. Seismic performances of URM walls could be effectively improved by interlocking masonry units. 続きを見る

概要: We investigated the 2004 Niigata-Chuetsu earthquake, where we have both strong ground motion records and building damage data, examining correlation between various indices of seismic destructive power and building damage. We confirmed that the average elastic velocity response in the period range of 1 to 2s with a damping factor of 0.05 which one of the authors proposed as an optimum destructive power index of strong ground motion for predicting building damage has close correlation with actual damage to buildings also in the case of the 2004 Niigata-Chuetsu earthquake. The period range is based on the equivalent periods that are calculated for buildings with typical elastic periods considering inelastic elongation. A vulnerability function of wooden houses for same seismic intensity in the case of the 2004 Niigata-Chuetsu earthquake was smaller compared to that in the case of previous earthquake, such as the 1995 Hyogoken-Nanbu earthquake. 続きを見る

概要: We investigated the 1994 Northridge, California, earthquake, where we have both strong ground motion records and building damage date, examining correlation between various indices of seismic destructive power and building damage. We used correlation analyses, maximum likelihood method and correlation analyses considering the number of buildings ground strong ground motion observation points, We confirmed that the average elastic velocity response in the period range of 1 to 2 s with a damping factor of 0.05 which one of the authors proposed as an ontimum destructive power index of strong ground motion for predicting building damage can be used in the case of buildings in California, USA The period range is based on the equivalent periods that are calculated for buildings with typical elastic periods considering inelastic elongation. 続きを見る
