翻新旧结构时，您需要知道多个建筑组件的一般条件。一个可以决定翻新程度的组成部分是建筑物的地板结构及其装载能力。由于负载能力确定因结构而异，因此了解该组件对于评估旧结构至关重要。

结构评估

通过利用专门的工程和测试公司的专业知识，可以找到答案evaluating structures. Evaluations can range from taking existing historical documents and comparing them with the as-built conditions, taking samples of building material back to a lab to perform mechanical testing to “reverse engineer” the floor structure or even performing full-scale load tests on the structure. If the load capacity results do not meet desired requirements, then the analysis and testing results can help develop construction details for rehabilitation as well as the economic feasibility for the extent of the rehabilitation. This type of assessment is beneficial for buildings in areas undergoing a “rebirth” to either repurpose or revitalize commercial and multi-use districts.

If no drawings or documentation are available and sampling materials is not an option, then an alternative approach may be researching an applicable building code from the same time period and establishing a possible minimum live load required for the original intended use of the structure. Exploratory, selective demolition can then be utilized to reveal hidden or concealed structural systems, such as steel beams or columns, which can be measured and compared with historical material properties to determine an allowable load capacity.
