Its shareholders sold an additional 21.5 million shares, according to the Associated Press."Through the strong reputation and universal appeal of our brand -- enabling extensive word-of-mouth exposure and outsized earned media value -- we have efficiently built a growing global fanbase of millions of consumers that uniquely transcends geography, gender, age and income," Birkenstock said in a recent regulatory filing with the Securities and Exchange Commission, according to the AP.What started out in 1774 as a somewhat frumpy, but functional arch support sandal has transformed into a cult fashion item and billion dollar business, bolstered with support from the recent blockbuster hit "Barbie" when Margot Robbie's character is forced to choose between high heels or the strappy suede footwear.In tandem with the opening on Wall Street, Birkenstock hosted three consumer activations in public parks throughout Manhattan and Brooklyn.To highlight New York as "the city that never stops walking," the brand created what it dubbed "Birkenfields" for a public sensory experience that explored the brand's nearly 250-year heritage and expertise in foot health.The global brand is deeply rooted in foot health maintenance as well as a family tradition of shoemaking: Its inventor sought to provide function, quality and tradition as Birkenstock's core values.Over 95% of Birkenstock products are assembled in Germany with more than 90% of their materials and components sourced from Europe, ensuring the brand meets "the highest environmental and social standards in the industry by operating state-of-the-art scientific laboratories for materials testing," according to a company press release.。此前,深中通道中山大桥、非通航孔引桥已完成荷载试验。

B | 深中通道桥梁工程顺利通过“大考”,朝着今年6月具备通车条件又迈进关键一步。深中通道是世界级“桥、岛、隧、水下互通”跨海集群工程,全长约24公里。其中,桥梁工程总长约17公里,包括伶仃洋大桥(悬索桥)、中山大桥(斜拉桥)和非通航孔引桥。荷载试验是大桥通车前必须经历的关键环节,分为静载试验和动载试验。通过等效模拟通车后的荷载情况,现场测试桥梁各部位的反应数据,判断桥梁承载能力是否符合设计要求和相关规范要求,为今后长期健康监测提供初始数据,也为日后养护、管理的决策提供科学依据和支持。

C | 据悉,在最大荷载工况的伶仃洋大桥静载试验过程中,136辆总重约5000吨大货车分批行驶上桥,按照17行×8列的要求停放在桥面预先划定的停靠点,进行分级加载,实测主梁、主塔、主缆和吊索的位移和应变,并与理论值进行比较,从而评估桥梁工作性能。在动载无障碍行车试验中,两辆满载共70吨、相当于约45辆小汽车重量的载重卡车,以每小时10至60公里不等的时速在大桥上匀速行驶,通过布置在中跨中断面的动应变传感器,测试结构在行车荷载作用下的动力反应,分析得到桥梁的冲击系数。“从目前掌握的数据来看,深中通道伶仃洋大桥、中山大桥、非通航孔引桥的实测值均小于理论值,且大部分指标富余较大。这意味着,深中通道桥梁工程不仅通过‘体检’,还可以说是在‘体能达标测试’中取得了不错的成绩。”广东交通集团深中通道管理中心副主任姚志安表示。

D | 目前,深中通道的机电、交安、路面、房建附属等工程正在全力推进,为6月具备通车条件冲刺。项目建成通车后,深圳至中山的车程将从目前的约2小时缩短至30分钟内。
