Cross-sectional capacity of oval hollow structural sections

钢结构传统上广泛使用现成的梁和柱。Ankor Engineering是一家加拿大公司，专门从事建筑通道和安全系统的设计，制造和安装。一个这样的系统利用伸缩式和单长度支腿臂，从建筑物侧面悬臂到30米，以支持设备和维护工人。Ankor开发了一种空心（管状）钢截面，称为椭圆形空心结构截面（OHSS），其几何形状针对这些应用中的应力进行了优化。然而，由于它不是标准产品，例如加拿大结构钢设计规范中可用的标准设计方法往往过于保守。

Steel structures have traditionally made extensive use of off-the-shelf beams and columns. Ankor Engineering is a Canadian company specializing in the design, manufacture and installation of building façade access and safety systems. One such system utilizes telescoping and single length outrigger booms that cantilever up to 30 metres from the side of a building to support equipment and maintenance workers. Ankor has developed a hollow (tubular) steel section, called an Oval Hollow Structural Section (OHSS) with a geometry optimized for the stresses that develop in these applications. However, because it is not a standard product, the standard design approaches available in the Canadian structural steel design code, for example, tend to be over-conservative.
