英国土木工程论文代写:建筑的劣化

荷载对结构的应力:荷载作用下结构有明显的应力。主要的结构元素受荷载的影响,悬挂在人行道的树荫下。这些横幅被认为是对整体压力的贡献。风力和雨是其他一些促成因素。
水:在结构的水不会导致结构的锈蚀,但仍可能有木材降解(卢里,与Crewdson,1994)。用于保护的油漆也会随着时间的推移而退化,除非使用保护性维护,否则它们不会有效地保温。
环境条件:屋顶和天花板的工作主要用于隔热。隔热层能有效地抵抗太阳的热量,也能确保对流热停止。屋顶结构通常与不可燃的薄膜相叠加。这称为衬垫。衬垫将确保反射隔热是有效进行(Al Hammad等,1997)。然而,这种形式的绝缘需要不时重新安装,当不经常维修这种结构时,它在环境压力下逐渐失效的可能性增加。
化工过程:这是用于建筑建材生态将在耐久性起着重要的作用,建筑的生存(Berger,2009)。某些清洁剂可能被用来清洁屋顶的延伸,有助于直接分解,特别是如果食物是混合的树汁和硬木。一些清洁剂可能间接导致建筑物的劣化,因为它可以软化表面上的油漆,从而保护建筑物。在更直接的相互作用(moncmanova,2007),变质效果会更快,而在其他情况下,恶化的影响将更为长期和长期可以做同样的水平,如果不是更多的伤害。

Stress on the structure from loads: There is obvious stress on the structure of the loads. Primarily the structural elements are affected by loads in the form of banners that are hung under the walkway shade. These banners are seen to be contributing to overall stress. The wind force and rain are some of the other contributing factors. Stress on the structure from loads: There is obvious stress on the structure of the loads. Primarily the structural elements are affected by loads in the form of banners that are hung under the walkway shade. These banners are seen to be contributing to overall stress. The wind force and rain are some of the other contributing factors.  Water: Water on the structure will not lead to the rusting of the structure, but there might still be wood degradation (Lewry, & Crewdson, 1994). The paint used for protection could also degrade with time, and unless protective maintenance is used, they would not work for insulation as effectively as they should.  Environmental Conditions: The roof and ceiling work for the main purpose of insulation. Insulation will effectively work against the heat of the sun and will also ensure that convection heat is stopped. Usually the roof structure is superimposed with a non-flammable thin membrane. This is termed sarking. The sarking will ensure that the reflective insulation is carried on effectively (Al-Hammad et al, 1997). However this form of insulation will need to be retro fitted from time to time, when constant maintenance is not given to this structure the chances of it failing gradually under environmental stress increases.  Chemical Processes: Ecology of the building materials that are used for construction will play a major role in the durability and the survival of the building (Berge, 2009). Certain cleaning agents that might be used to clean the roof extension could contribute to the disintegration directly, especially if the food used is a mix of sap and hardwood. Some of the cleaning agents might indirectly lead to the deterioration of the building because of its working to soften the paint that is present on the surface which will protect the building. In the more direct interaction (Moncmanova, 2007), the effects of deterioration will be faster, and in the other case the effects of deterioration will be more prolonged and in the long run could do the same level and if not more of damage.
