新西兰土木工程论文代写:抗剪程度

如果建筑物的抗剪强度不能保持一致,可以以生命损失,资产,建筑施工投资和劳动时间浪费的形式遇到巨大的经济代价。
为了应对高强度结构的要求,有一套称为统一建筑规范(UBC)的建筑规范,其中规定了针对生命安全所必须设定的可能危害的目标。然而,UBC在经历了一场自然灾害后,并不鼓励建筑物的利用。
最有可能发生的损坏和建筑受到的恶化来自地震和飓风的影响。这种可能性揭示了改进结构的需求,不仅对新建筑物而且对现有的结构进行改进,从而可以采用改造技术。 (Adedeji,2011)
在引入UBC之前,传统建筑的建设对于剪力所需的抵抗力没有太多的关注。因此,这些结构堆积在可以忽略的抗剪力和微小的立场上,抵抗基础等引起的隆起(Adedeji,2011)
木墙的结构设计使它们由垂直的框架构件组成,水平构件通过钉子连接。在这个阶段之后的后改进使用对角线的木制大括号或在带有瓦片或外层的墙壁上的对角线方向上部分铺板以防止天气条件并且还用于整理目的。 (Adedeji,2011)
在我们进入新时代的过程中,正在强调在极端条件下对建筑性能的重要性的专门知识,正在采取步骤加强结构的性质。这也是UBC强制的,现在它意识到了它的意义。 (Adedeji,2011)
建筑物在地震情况下的表现处于持续改善状态,其中一个步骤就是使用形状记忆合金作为剪力木墙体的增强材料。

If the shear resistance of the building is not kept in accordance, great economic costs can be encountered in the form of the lost lives, assets, the investment on building construction and the wasted hours of labour work.
In order to deal with the requirement of high strength structures, there is a set of building codes known as Uniform Building Codes (UBC) which defines the objectives set against the probable hazards that must be set for the safety of life. However, UBC does not encourage the utilization of a building after it has been through some natural disaster.
The most likely to occur damage and deterioration that building gets subjected to are from seismic and hurricane affects. This likelihood has revealed the demand for improved structures with improved designs not only for new buildings but also for the existing structures whereby retrofitting technique can be employed. (Adedeji, 2011)
Before the introduction of UBC, the construction of conventional buildings did not pay much attention to the resistance that was needed against the shear forces. Hence, the structures were composted of negligible shear resistance forces and minute stand back against the resultant uplift from foundations, etc. (Adedeji, 2011)
The structural setting of the timber walls was such that they were made up of vertical frame members only with horizontal members attached across via nails. The post improvement after this stage made use of diagonal wooden braces or partial-planking in a diagonal direction in the walls with shingles or outer layer to protect against the weather conditions and also to serve the finishing purpose. (Adedeji, 2011)
As we have entered into the new era, the know-how of the significance of the building performance under extreme conditions is being emphasized and steps are being taken to enhance the properties of the structure. This has also been made compulsory by UBC which now realizes the significance of it. (Adedeji, 2011)
The performance of the buildings in earthquake situation is in a continuous state of improvement and one such step is the employment of shape memory alloy as reinforcement in shear timber walls.
