Experiment study on RC frame retrofitted by the external structure

Earthquake Engineering and Engineering Vibration 2016年第3期15卷 563-574页

作者： Liu Chunyang Shi Junji Hiroshi Kuramoto taguchi takashi Kamiya takashi College of Civil Engineering Shandong Jianzhu University Division of Global Architecture Graduate School of Engineering Osaka University Earthquake Engineering Technology Institute Yahagi Construction Co. Ltd

A new retrofitting method is proposed herein for reinforced concrete （RC） structures through attachment of an external structure. The external structure consists of a fiber concrete encased steel frame, connection slab and transverse beams. The external structure is connected to the existing structure through a connection slab and transverse beams. Pseudo- static experiments were carried out on one unretrofitted specimen and three retrofitted frame specimens. The characteristics, including failure mode, crack pattern, hysteresis loops behavior, relationship of strain and displacement of the concrete slab, are demonstrated. The results show that the load carrying capacity is obviously increased, and the extension length of the slab and the number of columns within the external frame are important influence factors on the working performance of the existing structure. In addition, the displacement difference between the existing structure and the outer structure was caused mainly by three factors： shear deformation of the slab, extraction of transverse beams, and drift of the conjunction part between the slab and the existing frame. Furthermore, the total deformation determined by the first two factors accounted for approximately 80% of the damage, therefore these factors should be carefully considered in engineering practice to enhance the effects of this new retrofitting method.

Physical Properties in Aqueous Solutions for a Series of Alkyltrimethylammonium Salicylates (C12TA-Sal through C16TA-Sal): From a View Point of Drag Reduction

引用

Soft Nanoscience Letters 2016年第4期6卷 45-55页

作者： Yasushi Yamamoto takashi Arai takashi Tomita Zameer Shervani Akihiro Yoshino Keijiro Taga Shinji Tamano Motoyuki Itoh Yoshitaka taguchi Graduate School of Engineering Nagoya Institute of Technology Nagoya Japan Chukyo Yushi Co. Ltd. Nagoya Japan

Compounds for a series of alkyltrimethylammonium salicylates (C12TA-Sal through C16TA-Sal) were synthesized. Their physical properties in aqueous solutions were investigated by conductometry, viscometry, vortex inhibition, viscoelastic recoil and swirling decay time from a view point of drag reduction. For critical micelle concentrations (CMC) obtained for a series of compounds by conductometry, it was found that a linear relation of the form, log(CMC)= 4.088﹣0.305*Nc (Nc: carbon number in the alkyl chain), holds. From the viscosity measurement, all the compounds showed viscosity increase above their CMC. Vortex inhibition was observed above the CMC for the compounds with the chain length longer than C13. Viscoelastic recoil was observed above the concentration of one and a half times the CMC for the compounds with alkyl chain length longer than C14.

Piezoelectric Power Harvesting via Acoustic-Pressure Driven by Low-Speed Wind-Force with Resonating-Tube and Wind-Collector

引用

Journal of Power and Energy Engineering 2018年第11期6卷 53-64页

Wind-driven power harvestings attract attentions since their target wind speeds are quite low less than the so-called cut-in wind speed, which is generally recognized as around 3 m/s. The extant power harvestings driven by wind-induced-air-column-resonations (i.e. acoustic-pressures) are still lacking simplicity, scale flexibility and solid strategies for practical applications. Therefore, the piezoelectric power harvesters via acoustic-pressures driven by low-speedwind-forces with resonating-tubes and wind-collectors were invented so as to complement all the lacks. The wind-collector as well as the resonating-tube contributed to upraise the power harvesting density. The champion power harvesting density of 19.5 nW/dm2 could be procured at 2.3 m/s of an artificial wind and the optimal resonating-tube and wind-collector. Power harvesting proofs from the natural wind with low mean speeds down to about 0.6 m/s were successfully obtained. The cut-in wind speed of the prototype piezoelectric power harvester was found to be quite low as about 0.4 m/s, signifying its ubiquity. Finally, a multi-bundle pendant-type piezoelectric power harvester was specifically presented together with professing the solid and multiple strategies for practical applications.

改变二乙醇酸(DGA)的添加量和聚丁二酸丁二醇酯PBS缩合聚合,得到了数均分子质量达6.5万以上的P(BS-co-DGA)二元无规共聚物。使用核磁共振表征了共聚物的化学结构,根据不同DGA的添加量对共聚物的相对分子质量、热性质、力学性能、降解性的影响等进行了研究。结果表明:P(BS-co-DGA)共聚物在较短的反应时间内具有相对高的数均分子质量,分子量分布在2左右;随着DGA添加量的增加,共聚物的Tm和△Hm呈降低趋势;但是所有共聚物的热稳定性没有大的改变,热分解温度均在300℃以上;DGA添加量为2%时在堆肥中的降解速度最快。
