Abstract: To study the reinforced concrete beam stress performance under ultra-low temperature, Monotonic static load tests of 6 reinforced concrete beams were conducted at a temperature range from -180 oC to -40°C by using home-made jig and fixture for low temperature. The failure modes and the mechanical properties of the reinforced concrete beams under low temperature were investigated. The test results showed that both the bearing capacity and the stiffness of the beams increased with the decrease of the temperature. Based on the material constitutive and mechanism at ultra-low temperature, the numerical simulations are implemented and component test is expanded by using DIANA software environment.

Abstract: This paper put forward successful integration of SWH systems into a building and propsed feasible way to realize.Application to apartment buildings in Jianda Districts is used as an example to demonstrate the whole building integration approach.And the practicality is discussed to evaluate what type of BISWH will be needed.

Abstract: Concrete is the most common material used in buildings and its performance is improving. The plant-growing concrete was developed for conveniently greening. The plant species to able to grow in the plant-growing concrete was few. The habitat of plants grown in the plant-growing concrete is very similar to Karst soil environment. The plants of adaptability to Karst were adapted to the Karst stresses of high calcium and pH, low nutrition and drought. The plant-growing concrete combined with the plants of adaptability to Karst can apply in ecological slope protection, roads and roofs greening, and vertical greening. The vertical greening by the plant-growing concrete combined with the plants of adaptability to Karst will enlarge the green areas, beautify the cities and increasing landscape diversity.

Abstract: Construction and control principle of the new combined steel lead damper (NCSLD) were introduced, pseudo-static tests of NCSLD which would be used in the subsequent shaking table tests were carried out for the study of its mechanical properties using electro-hydraulic servo press-shear machine. Structural seismic design procedure using NCSLD is presented. An engineering example of seismic strengthening using NCSLD is provided. Results of tests and analyses indicate that NCSLD has full hysteresis loops which take on bilinearity; NCSLD is of strong energy dissipation ability and has obvious control effects for structural inter-story displacement and acceleration reactions.

Abstract: Architecture is a carrier of culture, as well as a product of one certain historical period. Influenced by the traditional culture over a long period of time, Huizhou folk houses have formed their own decorative design style with unique regional features. The article explores the design ideas on the decorative art of Huizhou ancient folk houses through formation and development of the decorative style, decorative characteristics, adornment subjects and decorative crafts. Based on it, the article excavates modern significance and value of the decorative art of Huizhou ancient folk houses, trying to get some references and enlightenments on modern architectural decorative design.

Abstract: In recent years, investment on China’s exhibition buildings rises sharply, but problems like over-warming of the exhibition hall construction, structural surplus, and low utilization rate occur. On the basis of analyzing the current development status of China’s exhibition buildings, this paper takes Nanning International Convention & Exhibition Center as an example to develop the investigation and study, and proposes the sustainable development strategy pointedly from building space environment and planning management, etc. The study is expected to provide reference for the sustainable development of similar domestic exhibition buildings.

Abstract: This paper proposes AHP-FCE model with dynamic weight for the operational phase of school public building, to determine the energy saving coefficient of unit Office, and then evaluate energy efficiency of the whole building during running period. Paper introduces the concept of degree of weight effect, to quantify the impact of factors on the overall evaluation result, explains the idea of energy saving coefficient, to measure the building energy efficiency. Based on degree of weight effect, we get weight adjustment vectors to calculate energy saving coefficient. Through the energy monitoring system based on Green IT, paper shows that the proposed model can reflect the energy efficiency accurately and in time, rather than simply reflect how much energy is consumed.

Abstract: Based on long-term testing and recording of room temperate in a bedroom of residential buildings in the hot summer and cold winter zone, this assay focuses on comparative analysis of tested results and simulated results derived from the DeST software. It verifies the rationality and reliability of the DeST software, showing the feasibility that software DeST can be applied to analyze the energy consumption of residential building in hot summer and cold winter zone.

Abstract: According to the problems of the existing air conditioning system of the telecom building, a new air conditioning energy optimization control system was designed and constructed. In this system, a refined control that covers from the cold source to the air conditioning terminal units can be achieved. The system worked efficiently by applying various control technologies. It is reliable and easy to operate. Significant energy savings has been achieved since its application in 2010.

Abstract: The influencing factors of partnership formation in construction industry are studied using a meta-analysis. The results show that trust, commitment, interdependence, joint problem solving, information sharing, conflict resolution and joint action are positively associated with partnership formation in construction industry.
