As a result, the historic centres of towns and cities are deteriorating, while their suburbs are spreading. One of the main problems affecting the rehabilitation of residential buildings is that it is extremely difficult to accurately estimate the costs involved. Although there are established methods （and technical documents available） to aid the costing of new buildings, there is a lack of official information about the costs of rehabilitation work, particularly as regards the external envelope of buildings. This article demonstrates how to determine rehabilitation costs （with particular emphasis on the envelope of residential buildings） by gathering information from specialized companies, assessing price variability and consulting databases of rehabilitation costs from other countries. It also presents some examples of costing for particular rehabilitation jobs.展开更多

Plenty of literatures can be available about simply supported composite slabs with single span. However, continuous slabs always exist in high-rise building structures. In order to obtain the ultimate loading capacity of continuous composite slabs, the full scale test on slab specimens with high cost need to be carried out. This paper presented an analytical model for calculating the ultimate loading capacity of continuous composite slabs. Only the small-scale slide block test needed to be carried out for determining some mechanical parameters, resulting in less cost, compared with the conventional m-k test method. Various load conditions and parameters were considered in the analytical model. The comparison between test results and predicted results showed that the proposed method had enough precision. Furthermore, the simplified method was also proposed for practical design.展开更多
