Structural problems associated with excessive vibration of building floor systems when subjected to human rhythmic activities have been *** this context,this research work aims to develop an analysis methodology to evaluate the human comfort and assess the fatigue performance of steel-concrete composite floors when subjected to human rhythmic activities(aerobics).The investigated structural model corresponds to a steel-concrete floor with dimensions of 10 m×10 m and a total area of 100 m^(2).The numerical model developed for the dynamic analysis of the floor adopted the usual mesh refinement techniques present in finite element method(FEM)simulations implemented in the ANSYS *** investigated floor dynamic response was calculated through the consideration of people practicing rhythmic activities on the structure,in order to verify the occurrence of excessive vibration and to assess the human *** fatigue assessment is based on a linear cumulative damage rule through the use of the Rainflow-counting algorithm and S-N curves from traditional design *** results indicated that,in several analysed situations,the investigated floor presents excessive vibration and user’s *** the other hand,the structure service life values were higher than those proposed by the design codes,ensuring that the members,connections and joints will not fail by fatigue cracking.

高温环境中运动会引起体温调节和其它生理压力,继而可导致耐力运动能力的损害。本共识性声明的目的是提供最新的建议以使热环境中体育活动时的运动能力最优化。可用于降低热应激压力和优化运动能力的最重要干预方式是热习服,其应包括1~2周以上反复的运动—高温环境暴露。此外,运动员应在正常水合状态下开始比赛和训练,并将运动中的脱水最小化。随着商用降温系统（如降温背心）的发展,在高温环境中训练或比赛前,运动员可以采取降温策略来促进热的散发或提高蓄热能力。而且,赛事组织者应该设计大面积的遮阳区域,并提供降温和补水设施,按照最小化运动员的健康风险来安排赛事,尤其是在大众参与的赛事中及一年之中炎热天气开始之初。以最近的2008年奥运会和2014年国际足联世界杯为例,当比赛在高温环境中举行时,赛事主管机构应考虑在比赛中或比赛之间允许额外的（或更长的）恢复期以提供补水和降温的时机。

Photonics Research 2022年第4期10卷 I0001-I0009页

Many applications, including optical multiplexing, switching, and detection, call for low-cost and broadband photonic devices with polarization-independent operation. While the silicon-on-insulator platform is well positioned to fulfill most of these requirements, its strong birefringence hinders the development of polarizationagnostic devices. here we leverage the recently proposed bricked metamaterial topology to design, for the first time, to our knowledge, a polarization-independent 2 × 2 multimode interference coupler using standard 220 nm silicon thickness. Our device can be fabricated with a single etch step and is optimized for the O-band,covering a wavelength range of 160 nm with excess loss, polarization-dependent loss, and imbalance below 1 dB and phase errors of less than 5°, as demonstrated with full three-dimensional finite-difference time-domain simulations.
