As a response to ever denser cities, high rise buildings have become increasingly popular and are growing tallerthan ever. In addition, there is also a developing trend to use modularization that minimizes the constructionschedule and thereby reduces costs. A new efficient structural system for high rise building has been developedcalled the Super Frame (SF). SF structures divide a building structural system into primary and secondarystructures. The primary frames of the SF system are composed of vertical legs in each corner of the buildingwhich are linked by horizontal diaphragm elements at about every 10 to 20 floors. The primary frames resist allvertical, wind, and seismic forces as an exterior structure since the vertical elements are concentrated in thecorner areas of the building, maximizing resistance to the wind and seismic forces. The SF concept has beenrecently used in Asia and the Middle East [1]. However, for such buildings to be built in Canada, they mustconform to Canadian Building Code requirements [2] to ensure their serviceability limit state and ultimate limitstate design under high wind and earthquake loads. The total lateral deformation of the high rise must be underthe Canadian safety limits stated by the code to ensure safety and smooth operation of the high rise building'selevators; these benefits will, in turn, be passed onto rate paying customers.BAH Enterprises is an expert in the field of structural engineering for industrial projects with special emphasison powers stations, power plants (gas, coal, nuclear, wind and solar), electrical transmission projects, andindustrial buildings. BAH is interested in using a combined SF system of High Strength Steel (HSS) framesfilled with Ultra High-Performance Concrete (UHPC) for industrial buildings, as they offer numerousadvantages over other design structures, including lower costs, and more efficient use of space. BAH hasinvestigated the use of such SF designs for industrial buildings, but a lack a sufficient design model,particularly seismic modelling, has prevented practical implementation in projects thus far.

作为对越来越密集的城市的回应，高层建筑物变得越来越受欢迎，并且越来越高。此外，使用模块化的趋势也在不断发展，可以最大程度地减少构造修剪，从而降低成本。已经开发了一种新的高层建筑的高效结构系统（超级框架（SF））。 SF结构将建筑物结构系统分为主要和二级结构。 SF系统的主要框架由建筑物的每个角落的垂直腿组成，它们由水平隔膜元素在每10至20层大约20层链接。主要框架将垂直的元素集中在建筑物的塞子区域，从而最大程度地提高了对风和地震力的抵抗力，因此主要框架抵抗了全面的，风和地震力作为外部结构。 SF概念已在亚洲和中东使用[1]。但是，对于在加拿大建造的这些建筑物，它们必须符合加拿大建筑法规要求[2]，以确保其可使用的限制状态和在大风和地震负载下的最终极限状态设计。高层的总横向变形必须在《加拿大安全限制》下，以确保高层建筑物的安全性和平稳运行；反过来，这些好处将被转移到付费客户上。BahEnterprises是具有特殊强调力量站，发电厂（天然气，煤炭，核，核，风和太阳能）的工业项目结构工程领域的专家，电气传输项目和工业建筑。 Bah有兴趣使用高强度钢（HSS）组合的SF系统，以用超高性能混凝土（UHPC）用于工业建筑，因为它们比其他设计结构（包括较低的成本和更有效的空间使用）提供了大量的优势。 Bah对这种SF设计用于工业建筑，但缺乏足够的设计模型，尤其是地震建模，这阻止了迄今为止的项目实施。
