德克萨斯州达拉斯的一座11层的办公大楼将于2月16日在受控的拆除中被击倒，但爆炸掉落了建筑物的外壳，但未能降低结构的混凝土核心。

将近两个星期后，稍微倾斜的核心保持不变，并继续将其降低。拆除承包商，总部位于达拉斯的劳埃德·D·纳伯斯（Lloyd D.到达挖掘机以击倒其余的核心。

The former Affiliated Computer Services building consisted of a concrete core and precast concrete elements along the perimeter, with beams spanning in between. The central core, where the elevators and staircases were located, was stronger than the perimeter elements of the building, which came down as planned. The tower is being demolished as part of a $2.5 billion mixed-used redevelopment effort led by Dallas-based De La Vega Development. In the days since the tower's failed implosion, onlookers have gathered to take photos in front of the 'Leaning Tower of Dallas.'

Different types of structural systems often require different demolition approaches to bring them down, but the concrete core of the Dallas tower was not particularly unusual in its design. Yet as various eras of building design age out and are demolished, different techniques will be needed to safely demolish them, says Mark Loizeaux, president of Controlled Demolition, Inc.

Loizeaux的公司没有参与这一特殊的达拉斯塔拆除，但CDI过去拆除了类似设计和古董的结构。“与建筑中一样，拆除承包商及其客户必须对被拆除的结构的性质敏感。随着时间的流逝，新的和不同类型的施工正在拆除，并且在设计拆除，通过常规或爆炸性手段设计时必须注意这些不同的系统，” Loizeaux告诉Enr。新利18备用

In the case of the ‘Leaning Tower of Dallas,' Loizeaux declined to comment on what might have specifically gone wrong in the demolition of the building’s core. But he does add that “in this case, it may be that the developer or contractor didn’t pay attention to the type of construction, and certainly the developer might have been more thoughtful in considering if the contractor had experience in demolishing this type of structure.”
