Optimizing building performance and economic benefits through feedback in building design is a hot topic in current academic research. However, few studies on prefabricated buildings have been undertaken in this field. Meanwhile, the methodology used for achieving optimized solutions is still poor. In this paper, genetic algorithms and correlation analysis are employed and two parametric design methods—i.e., the floor plan generation method and the component selection method—are proposed for the modularity of the prefabricated buildings. Taking a typical high-rise building in Tianjin as an example, correlation analyses are performed on the basis of the two proposed methods to enhance the depth of the optimized finding approach. The outcome of this research demonstrates the feasibility of the proposed numerical approach, which can produce the optimized floor plan and construction set under the local conditions. This also reveals that the shape coefficient and window-to-wall ratio are strongly correlated with the energy performance of a building, which can help architects to pursue optimized design solutions in the schematic design process.

<p>       Under the northward push of the Tibetan Plateau, Qaidam basin is the intersection of Traim block, Bayan Har block and Qilian orogen. Inversion and interpretation of the crustal structure under Qaidam basin are helpful to understand the evolution of the plateau. On November 10, 2008, an Mw6.3 earthquake occurred in the northern margin of Qaidam basin and was recorded by 17 broadband temporary stations installed by the INDEPTH IV Project. We performed inversion of the recorded regional seismic waveforms combining niche genetic algorithm and reflectivity method and obtained the crustal velocity structure of the eastern, western and northwestern part of Qaidam basin.The inversion results show that the structures of the eastern and western basin are similar, where both exist a very thin low velocity layer at about 26km in the middle crust. The thicker lower crust of the west basin results in thicker crust than that of the east basin, which reveals decoupling of the upper and lower crust of the basin. The structure of the northwestern basin is quite different from other regions with much thicker crust, lower velocity of the lower crust and upper mantle, indicating strong deformation and partial melting.</p>
