UBC的校园充满了漏洞。一些建筑工地几乎遍布校园的每一个角落。有些是在一个等级，那里的历史数字地面是一个混合袋的建筑形式，死胡同和脱节的学术街区。有些在更高的地方，离地面-漂浮在树冠上。

The UBC campus is full of holes. Some are below ground where construction sites pepper nearly every corner of campus. Some are at grade where the historic figure ground is a mixed bag of building forms, dead-ends and disjointed academic neighborhoods. Some are higher up still, off the ground -- floating in the tree canopy.

该大学一直在努力弥补其结构上的这些差距，率先进行了大规模的公共领域改革，并为学生生活带来了无数的改善。最突出的事业之一是在大学林荫大道的校园正门。小的，但不可或缺的林荫大道的重新开发，是两个战略插入的过境基础设施，为无轨电车环路提供有掩护的住所。这些临时避难所在概念上扩展了附近的Katsura树线。细长的钢柱排列在交错的线上，支撑着一个覆盖玻璃的超大蜂窝木结构。

The University has been hard at work to address these gaps in its fabric, spearheading a massive public realm overhaul and myriad improvements to student life. One of the most prominent undertakings is at the main entrance to campus along University Boulevard. Small, but integral to the Boulevard’s redevelopment, are two strategic insertions into the transit infrastructure that provide covered shelter for a trolley-bus loop. The transit shelters act as a conceptual extension of the nearby line of Katsura trees. Slender steel columns are arranged in a staggered line and hold up an oversized cellular wood structure clad in glass.

从远处看，玻璃反射并填补了周围树木的缝隙，但当一个人走近时，木头就会显露出来，并产生行走在树枝下面的效果。这些掩蔽所帮助创造了一个很长的覆盖空间，继续沿着林荫大道延伸到校园的中心，而人行道基本上不受垂直结构的干扰，从而减少了大量行人交通的障碍。

From a distance, the glass reflects and fills gaps in the surrounding trees, but as one approaches, the wood is revealed and creates the effect of walking underneath branches. The shelters help create a long covered space, continuing the canopies of adjacent buildings down the Boulevard into the heart of campus while the sidewalk remains largely uninterrupted by vertical structure, reducing impediments to heavy pedestrian traffic.

庇护所的目的是创造一种视觉平衡之间的随机和规则的模式，在自然界中找到。以树冠为起点，结构探索从一系列梁开始，然后梁连接起来支撑玻璃。我们试图注入结构网格的运动，最重要的是，创造一个设计，既执行视觉和结构。

The shelters aim to create the kind of visual balance between random and regular pattern that one finds in nature. With the tree canopy as a starting point, the structural exploration began as a series of beams, then the beams connect to hold up glass. We sought to imbue that structural grid with movement and above all, to create a design that performs both visually and structurally.

经过一系列的模式探索，结构分析和制造场景，出现的形式是一个重复的五边形旋转和翻转沿其边缘。这产生了一个规则的模块，以便于制作和随机安排的视觉运动。它可以重复使用，不会重复。为了保持防护罩的轻盈和流线型，并赋予天篷漂浮的质量，结构元素承担多种任务；柱子充当雨水龙头，预制延展性长凳支持钢制地图箱，两者都适合柱间距，以提供防风林。

After a series of pattern explorations, structural analyses and fabrication scenarios, the form that emerged was a single repeated pentagon rotated and flipped along its edges. This produced a regular module for ease of fabrication and a random arrangement for visual movement. It repeats without becoming repetitive.  In order to keep the shelters light and streamlined, and to give the canopy a floating quality, structural elements take on multiple tasks; columns act as rainwater leaders, the precast ductile benches support steel map cases and both fit between the spacing of the columns to provide a windbreak.

一种自攻螺钉系统使这种结构成为可能，12，000颗螺钉直接钻入钢板，产生瞬间连接，消除典型螺栓连接可能发生的挠曲或屈曲的可能性。这种掩体更多的是木船而不是木材构造，它隐藏而不是表示连接，以实现节段之间的紧密配合，并保持蜂窝木结构的整体外观。

  A self -tapping screw system made the construction possible whereby 12,000 screws drill directly into the steel plates creating a moment connection and eliminating the potential for deflection or buckling that might have occurred with a typical bolted connection.  The shelter is more about wood craft than wood tectonics, hidden rather than expressed connections to achieve a tight fit between segments and maintain the monolithic appearance of the cellular wood structure.
