与带有钢筋混凝土核心的钢制框架相比，高层侧侧负载抵抗系统的抵抗系统的绑扎双板墙模块的绑扎式墙壁模块的潜力（以削减上层结构构建时间）的潜力 - 持有庆祝的理由。纽约市建筑物已允许在纽约市使用该系统。
The city's acceptance is the second piece of positive news for the American Institute of Steel Construction (AISC), which filed for the New York City approval, and for the Lego-like system’s mastermind, structural engineer Ron Klemencic, chairman and CEO of Magnusson Klemencic Associates (MKA). Recent火灾测试showed the steel-plate walls do not need costly fire protection, known to slow construction.
Klemencic是E新利18备用NR 2018年卓越奖，他的研究传福音奖得以设计和建筑创新，例如SpeedCore，称纽约市的批准是“又一步的一步”。
New York City’s nod is likely to increase SpeedCore’s popularity, says Lawrence F. Kruth, AISC’s vice president of engineering and research.
Kruth, who had filed the alternate material application for SpeedCore about 18 months ago, received the news in an acceptance letter dated July 17 from the New York City Office of Technical Certification and Research. Among its other functions, OTCR evaluates new technology that enhances safety, sustainability and efficiency.
OTCR信件说，该系统对AISC具有重要意义，因为它为该系统用作“在建造高层建筑物中的横向支撑壁系统以抵抗风负荷和地震载荷的方式”。
Material and Equipment Acceptance
The OTCR letter only addresses material/equipment acceptance. Project approval and permits must be obtained from the Dept. of Buildings through the required application process, in compliance with the New York City Construction Code.
Prior to approval, SpeedCore must comply with additional design, filing, permitting, installation and inspection requirements. The AISC Design Guide 32 “Design of Modular Steel-Plate Composite Walls for Safety-Related Nuclear Facilities” may be used as guidance on how to apply AISC 360 and AISC 341 specifications for the design of SpeedCore,” says OTCR, in its letter to Kruth.
For each SpeedCore project, the city is also requiring peer review for all structural design and calculations: “The reviewer must review and certify that all design, calculations, details, installation and inspection are in accordance with New York City Construction Code. The reviewer(s) shall be retained by the owner and shall be approved by the buildings department prior to commencing the review." The reports of peer reviews “shall be signed, sealed and filed as a required item prior to construction document approval,” states the acceptance letter.
In addition to the usual requirements for plan approval and permits, a SpeedCore project is subject to special inspection.
The letter states a warning: “In the event of noncompliance with any of the requirements listed above or unresolved system failure during operation, the SpeedCore will be required to be removed at the owner’s expense.”
Guide to Bolted Version of SpeedCore Coming
研究人员正在为SpeedCore的现场螺栓固定版制定设计指南，在经常需要预热焊缝的寒冷气候下，这可能更快。Kruth说，由于AISC赞助的螺栓版本的研究已被延迟了几个月，这是由于Covid-19的大流行。他预计设计指南将于明年最新发布。
Rainier Square Tower, MKA’s 850-ft-tall proof of concept for SpeedCore, is nearing completion in Seattle. The Erection Co. Inc., led by its founder, CEO and 2019 ENR Newsmaker Adam Jones, erected the structure in only 10 months.
Klemencic说，正在为MKA的第二Speedcore项目开挖，这是一座20层的建筑，名为200个公园大道，位于加利福尼亚州圣何塞市。总承包商是10级。ShuffSteel是制造商 - 主管。墙模块的接头将被焊接，就像雷尼尔广场塔一样。
MKA is currently designing two schemes for a Boston project—one with a field-bolted version of SpeedCore and one with a structural concrete core. This fall, Turner Construction Co. will evaluate the schemes for cost, speed and risk. Klemencic declines to reveal any more details about the project.
