Aerodynamic admittance of along-wind loads on tall buildings

高层建筑顺风向的脉动风荷载通常是基于准定常假设,由来流风速的功率谱密度函数和相干函数求得,其中风荷载和风速功率谱密度对气动导纳函数影响较大。依据; 10个典型高层建筑模型的同步测压风洞试验数据,对高层建筑各层高度处顺风向荷载的功率谱密度函数和气动导纳函数的特性进行分析,提出了顺风向荷载气动导; 纳函数的表达式,并针对公式中的具体参数进行了拟合。采用该表达式对一栋实际高层建筑的顺风向风致动态响应进行计算,并与其模型的试验结果进行对比。结果; 表明:高层建筑顺风向荷载的气动导纳曲线沿高度变化不大,但与其截面形状关系较大,曲线整体呈指数分布,当折减频率小于0.1时,气动导纳数值均接近于1; .0。算例结果表明,采用所建议的气动导纳拟合式计算出的风致响应结果与风洞试验计算结果较为吻合,误差在10%以内。Along-wind fluctuating loads on tall buildings are usually obtained by; power spectra and coherence functions of inflow wind velocity based on; the quasi steady theory. In this process, the aerodynamic admittance of; along-wind loads plays an important role. Ten tall building models with; different section shapes were tested using simultaneous pressure; measuring technique in a wind tunnel. According to the test data, the; power spectra and aerodynamic admittances of along-wind loads on every; layer in the terrain category B and D were analyzed in detail and the; fitting formula of the aerodynamic admittances was proposed. Parameters; in this formula were given accordingly. The wind-induced responses of an; actual high-rise building were calculated by the formula given here and; random vibration method based on wind tunnel test data respectively. The; results show that the aerodynamic admittances of along-wind loads on; different height of the same tall building have little discrepancy and; vary with the section shapes. All of the aerodynamic admittances satisfy; the exponential law and approach 1.0 when the reduced frequency is less; than 0.1. The response using present aerodynamic admittance agrees well; with one from the wind tunnel experiment and the error is less than 10%.国家自然科学基金重大研究计划重点项

近25 a 银川市城市化进程中热力景观格局演变分析

Abstract： Based on the Landsat images and statistical data，in this paper the urbanization process and thermal landscape dynamics of Yinchuan City were analyzed． The objectives of this study were as follows: ① To analyze the spatial and dynamic characteristics of urban thermal landscapes based on the landscape pattern index; ② To assess the influence of the urbanization process on the thermal landscapes; ③ To understand the relationship between the land use pattern and the land surface temperature ( LST) based on the distribution index． The results showed that there was a significant heat-island effect in Yinchuan City，and the high temperature area was consistent with the built-up area and the unused land． LST declined from the downtown to the suburbs，and an obvious difference of the dynamic characters of the thermal landscapes could be identified at the different stages of urbanization． LST for various land use had obvious discrepancies，the mean LST for the land use types was in a descending order of unused land，construction land，green land and water body． Different land use types had different thermal distribution at different stages of urbanization． The land use pattern influenced the urban thermal environment，especially the spatial distribution of green land and unused land affected LST more significantly

后危机时代福建外经贸的转型与发展

在由美国次贷危机所引发的全球金融危机中,福建省的对外经济贸易经受了严峻的考验,同时也暴露出一些不足。因此,在后危机时期,重新审视福建外贸发展的现状与存在的问题,分析后危机时期福建外经贸发展的新形势,探讨后危机时期福建外贸发展的思路与对策,不仅很有必要,而且意义重大

足球踝发生的三维光弹性力学研究

目的:阐明足球踝的发生机制,探寻易发生足球踝的踢球姿势和力度,并为临床治疗提供指导。方法:解剖成年男子右侧带足小腿,量化分析其生物力学性质,制作环氧树脂距骨模型及应力冻结,切片后光弹仪观测,分析结果。结果:①踝关节跖屈35°位时,距骨表面所受拉应力远大于跖屈45°位时。②以相同姿势踢近或踢远,踢近时距骨表面所受拉应力较大。③拉应力集中区域为内踝后部、后踝中部及内侧,以及距骨滑车关节面前部等部位。结论:①以跖屈35°位的姿势踢球会增加足球踝的发生率。②高频率、小力度、踢近的踢球方式,会增加足球踝的发生率。③踢球对踝关节所造成的损伤主要集中在内踝后部、后踝中部及内侧,以及距骨滑车关节面的前部等

siRNA的化学修饰和临床应用

RNA干扰(RNAi)是目前分析基因组功能及基因治疗的一个有力工具,引起基因沉默现象的小干扰RNA(siRNA)需要经过适当的化学修饰才能应用于体内。该文总结了既能稳定siRNA双链,又能有效抑制靶基因的几种常用化学修饰法,包括磷酸骨架修饰、核糖修饰和碱基修饰等。正确的修饰将会极大地促进RNAi药物从体外到体内、从实验室到临床应用的转化。siRNA作为一种很有潜力的药物将为治疗病毒性疾病、肿瘤和遗传病开辟一条崭新的道路。厦门大学引进人才基金资
