Structural mechanism of traditional wooden frames by dynamic and static tests

Structural Control and Health Monitoring (2005)

Yoshiyuki Suzuki M. Maeno

This paper deals with the structural mechanism of traditional wood frames to evaluate the seismic performance of wooden buildings like Japanese temples. The outline of shaking table tests and static tests using several scale models is described and typical experimental results are discussed. From experiments, it is found that the horizontal restoring force of wooden frame without walls depends mainly on the bending moment resistance from tie beams and the restoring force due to column rocking. The equilibrium relationship between the total restoring force and all the bending moments involved is established and verified. Using this equilibrium relationship, it is possible to evaluate the restoring force due to column rocking. The restoring force due to column rocking is the major part of the total restoring force when the frame deformation is small. The bending moments from tie beams become dominant as the deformation increases. The traditional wooden frame has the large flexibility and deformability. It is essential to take advantage of the structural mechanisms found from this study in the seismic and enhancement design of traditional wooden buildings. Copyright © 2005 John Wiley & Sons, Ltd.

EVALUATION OF SHEAR STRENGTH OF TRADITIONAL WOODEN FRAME WITH HANGING AND WINDOW-BACK WALL

AIJ Journal of Technology and Design (2013)

Masato Nakao Masami Gotou Yoshiyuki Suzuki

Static shear loading tests on single full-height walls, hanging walls and window-back walls using dry-mud panels were conducted. And then, push-over analysis of combinations of the walls was performed, it was found that summation of shear forces of the single walls is higher than the shear force of combined analysis model except for the range of relatively large deformation. Consequently, to evaluate shear strength of traditional wooden building with dry-mud panel, summation of shear forces of the single walls was found to be adequate.

Pharmacological analysis of SGLT2 inhibitor (tofogliflozin) using in vivo glucose clamp and titration protocols in rats and cynomolgus monkeys

トホグリフロジン水和物（以下トホグリフロジン，製品名：アプルウェイ®錠，デベルザ®錠）は中外製薬株式会社によって創製された選択的ナトリウム－グルコース共輸送体（SGLT2：sodium glucose cotrasporter 2）阻害薬である．麻酔下カニクイザル・グルコース滴定試験において，トホグリフロジンおよびフロリジン（SGLT1，2阻害薬）はグルコース滴定曲線のスプレイ領域を拡大させたが，尿細管グルコース最大輸送活性には影響をおよぼさなかった．麻酔下正常血糖ラットにおける尿糖排泄・内因性糖産生同時測定系において，トホグリフロジンによる尿糖排泄の増加は内因性糖産生の増大で代償され正常血糖が維持された．一方，フロリジンはトホグリフロジンよりも大きな尿糖排泄促進作用と内因性糖産生性増加作用を示したが，その血糖降下作用はトホグリフロジンよりも大きかった．麻酔下ラットグルコース滴定試験および正常・低血糖グルコースクランプ試験において，トホグリフロジンは高血糖下のグルコース再吸収を50％以上抑制したが低血糖条件下では抑制しなかった．一方，フロリジンは高血糖下の腎グルコース再吸収を50％以上抑制し，低血糖条件下でも腎グルコース再吸収を20～50％抑制した．腎グルコース再吸収におけるSGLT2の貢献程度は低血糖よりも高血糖条件下で大きく，選択的SGLT2阻害薬であるトホグリフロジンは低血糖下の尿糖排泄を惹起せず，低血糖リスクが低いと考えられた．

Profile Drag of Circular Cylinders with V-Type Grooves in Circumferential Direction Placed in a Uniform Flow

The Proceedings of Conference of Tohoku Branch (2002)

Yoshiyuki Suzuki Toshio Iijima Hiroshi Fujino

The profile drag of circular cylinders with v-type grooves in the circumferential, spiral direction and crossing at the angles of 60゜ was measured in the range of Reynolds number Re=1.5×(10)^4 to 7×(10)^4 in a uniform flow. An Eiffel type low speed wind tunnel in an experimental apparatus produces a muximum velocity of 21m/s at the blow down section of width 300mm and height 400mm. The effects of the groove direction and the roughness on the drag coefficient were examined experimentally. The measurement of profile drag was carried out a direct method using the strain gauge load cells. The roughness of the cylinder surface was shown by the ratio h/d of v-type groove depth h and the diameter d of test cylinder. V-type grooves crossing at the angles of 60゜ have a great effect on the profile drag of circular cylinders. As h/d increases, the drag coefficient for the circular cylinders dercreases abruptly at lower Re. The drag coefficient for the circular cylinders with v-type grooves in the circumferential and spiral direction did not show the characteristic change in the present experiment range.

A134 Development of equation for predicting water vapor generated at micro-explosion of W/O emulsified fuel droplet

The Proceedings of the Thermal Engineering Conference (2009)

Hirotatsu Watanabe Yoshiyuki Suzuki Takuji Harada Yohsuke Matsushita Hideyuki Aoki

This paper describes a mathematical model to calculate a mass of generated water vapor at micro-explosion by using the mass and energy conservation equations under some assumptions. To develop the mathematical model, single droplet experiment was carried out. A W/O emulsified fuel droplet suspended by thermocouple was heated by halogen spot heater, and micro-explosion was observed with high-speed video camera. During heating of droplet, the progress of the coalescence of dispersed water droplet was observed. The calculated mass of water vapor generated at micro-explosion was compared with mass of aggregated water droplet just before micro-explosion. As a result, the validity of the proposed model of micro-explosion was shown, and it was revealed that almost whole water droplet was changed to vapor at micro-explosion instantaneously.
