地震、台风自然灾害与火灾、爆炸等人为因素已对在役房屋造成了不同 程度的损伤甚至破坏。其次,当前房屋结构正朝着高层次、大柔度方向发展,因此在风载、地震荷载及周围环境作用下可能会产生危险振动。

房屋在施工过程中,由于被偷工减料等原因未能达到设计要求,还有房屋使用过程中的随意改造等,致使房屋使用安全难以得到保证。 　

房屋检测

房屋质量检测是运用一定的技术手段和方法，通过对既有房屋质量（而不是在建工程质量），特别是对其结构质量进行检查测定，实施动态监控，以起到保障人民生命财产的安全，促进现有房屋资源的充分、合理利用，保证社会的稳定作用，因此具有巨大的社会效益和经济效益。房屋检测又称房屋质量检测评估，是指由具备资质的检测单位对房屋质量进行检测，评估，并开具报告的过程。

Earthquakes, typhoons, natural disasters, fires, explosions and other man-made factors have caused varying degrees of damage or even destruction to the houses in service. Secondly, the current housing structure is developing toward a high level and greater flexibility, so dangerous vibrations may occur under wind load, seismic load and surrounding environment.

In the course of construction, the design requirements can not be met due to shoddy and other reasons, as well as the random renovation during the use of houses, which makes it difficult to ensure the safety of the use of houses.

Housing testing

The inspection of housing quality is the use of certain technical means and methods to ensure the safety of the lives and property of the people of the country by examining and measuring the quality of existing houses(rather than the quality of projects under construction), especially their structural quality. Promoting the full and rational use of existing housing resources and ensuring the stability of society, it has huge social and economic benefits. Housing testing, also known as housing quality testing and evaluation, refers to the process of testing, evaluating, and issuing reports on housing quality by qualified testing units.
