	Abstract:With the development of large span and heavy load modern engineering, concrete-filled steel tubular structures appear constantly. The joints of these structures are mostly multi-planar joints. In order to solve the problem of lacking of the investigation of multi-planar concrete-filled steel tubular (CFST) joints, the mechanical behaviour of CFST KK joints were studied through refined finite element simulation. Accurate finite element models of CFST KK joints were established by considering the material nonlinearity, the geometry nonlinearity, and the contact nonlinearity between the tube and the concrete. The spatial effect of multi-planar joints was be obtained by comparing with uni-planar joints. The FEM results showed that, the multi-planar carry-over effects had the maximum effect for the 60o CFST joints, the strength of multi-planar joints decreased compared with the planar joints, and the stiffness of them did not vary substantially. While for the 90o CFST joints, both the strength and stiffness of multi-planar joints did not vary substantially with the planar joints. This research can provide scientific basis for the design of multi-planar CFST joints, and effectively promote the application of CFST structures.

	Abstract:The Belt and Road initiative emerges as the new Chinese Government strategy of cooperation with neighboring countries. It will revitalize the existing Silk Road and build the Maritime Silk Road, which connecting South East Asia through the Indian Ocean heading to the Middle East and North Africa. It has the similarities with Indonesia Maritime Toll program. Indonesia involved in Maritime Silk Road has many opportunities offer to the foreign country come, invest, and participate in their economic development improvement. However, Indonesia Investment Coordinating Board state that Chinese Investment realization in Indonesia recorded no more than 10% in 2014. Therefore, this paper aims to elaborate the Chinese Belt and Road Initiative, by doing SWOT analysis of the China-Indonesia relation and investment condition, and analyze the impact of the realization of the development of Indonesian infrastructure descriptively. The output will be the discussion of the realization of the belt and road initiative whether bring positive impact to Indonesia's infrastructure development.

	Abstract:The free-running temperature is a essential indicator to evaluate the thermal performance of a passive solar house in early design. However a easy-fast, accurate, and dynamic prediction method is lacking for decision-making in early design. Exited accurate and elaborate methods need detailed building information and simulation tools, which are complex and time-comsuming. Besides, exited simpilied methods are still complex for architects or have large hourly error. This paper introduced the virtual sphere method to calculate the dynamic thermal storage of the room, and proposed a new quasi-steady method to predict free-running temperatur. The study on thermal storage performance of a wall indicated only a indoor-side thin effective thermal capacitance layer has dominated effect on thermostability of the indoor space, and the depth of thin layer can be determined by thermal penetration depth formula. In addition, the room effetive thermal capacitance can be equivalent to a virtual sphere, and the dynamic thermal storage can be fast calculated by fitted formula of the classic unsteady heat transfer of a sphere. Then the hourly room free-running temperature can be fast predicted. The empirical validion of a light-weight and a heavy weight passive solar house demonstrated the hourly prediction can be all within the deviation range of ± 3.0 C
