Abstract: The modes of structural tectonic methods are proposed and the mode of creative cooperation by architects and structural engineers in the conceptual design stage for giving full play to their respective advantages are encouraged for joint design of architectural forms that meet structural safety requirements by this paper through analysis on functions and positions of structures in the architectural form framework system.The key function of observing the principle of structural correctness in the modes of architectural form design based on structural safety requirements is made clear.

Abstract: Multiple longitudinal unified times are spread out laterally by this paper through analysis on ancient Greek temples, ancient Romanesque arched architecture, Gothic churches, domed architecture and other western classical architectural forms in various historical periods, and five types of relations between architectural forms and structures are found out through summarization in combination with contemporary technological characteristics. The conclusion is that harmonic coexistence of technology and art can be truly achieved through architectural form creation on basis of respect to the laws of structural science and through active cooperation between architects and structural engineers.

Abstract: Seismic performances of high-rise buildings are urgent to be studied given the background of the 2011 off the Pacific coast of Tohoku earthquake and probable long-period ground motions happened in subduction zone near east-coast of Japan. One 20 story frame of CFT and steel high-rise buildings were modeling, and seismic responses of models were simulated in FEM program with fiber model subjected to extreme ground motions recorded in the 2011 off the Pacific coast of Tohoku earthquake and the relevant artificial ground motions. Analysis results indicate that, the frame models could not satisfy the seismic demand under extreme ground motions. The CFT model has superior ultimate stability behavior than steel model as result of confinement effect of confined concrete to steel tubular. The phenomenon of deformation concentration along with vertical direction becomes more intense when the inputting acceleration level arrives extremely higher.

Abstract: The bearing capacity of the all-steel BRB consists of a rectangular core plate and a square outer tube is analyzed by finite element method using ABAQUS. The influences of configuration parameters, including the initial eccentricity of the core, the ratio of the width to the thickness of the core, and the ratio of the gap to the width of the core, on the critical constraint ratio are investigated. The fitted equation obtained based on the analysis can be used to guide the design of the BRB.

Abstract: Abstract. Damping, as one of the most important indicators of the structure’s dynamic behaviors, depicts how energy dissipates during vibration. Using Hammering Method on Reinforced Concrete Simply Supported Beam model dynamic experiment, by analyzing the vibrating signals captured during hammering process, how the allocation of the sensors and the hammer strength affect the parameter identification can be revealed. A rational method of parameter identification can be presented as well.

Abstract: This article is generally based on the research on the methods of the census of the basic information and energy consumption of constructed buildings in Xi’an. And though the census we can build up a comprehensive database for launching the energy-saving work of constructed buildings in the city, and also to provide a further scientific and reasonable research on energy saving policies making, and further more to provide scientific basis for achieving the target of sustainable development.

Abstract: Urban culture is the foundation of the development of city，and discussions on its inheritance have been held for a long time. It is necessary to protect the space-time characteristics of historical heritages and absorb the contemporary elements. Only in this way, can we ensure the cultural life of historic blocks, and offer it new meanings.

Abstract: The article is composed under the background of Tibetan culture. Tibetan residence and settlement is the object of study, and inspection is conducted on architectural and cultural aspect of Tibetan region. The common feature of the architecture in the area is summarized, along with the typology of the architectures. Characteristics of Jiarong Tibetan residence are analyzed through comparison, the principle and ideas of development of traditional residence of Jiarong Tibetan is proposed.

Abstract: Grid shell is a new type of single layer latticed shell. Joint connections of this structrue always adopt semi-rigid joints: in-plane pin joints, out-plane rigid joints. A parametric modeling method using self-designed program is proposed in this paper. Bearing capacity of the elliptic paraboloid grid shell with semi-rigid joints is analyzed. Then, the influence of section of steel bars, rise-span ratio and initial imperfection on the bearing capacity is investigated.

Abstract: An method of calculation the displacement of wall pier in plastic zone under lateral force and axial force is proposed in this paper, which can reflect the failure behavior of wall pier at ultimate state observed from 9 RC slender solid shear wall specimens under reserve cyclic loading, and the contribution of both modes of flexural and shear deformation are considered. The comparison between analytical results and experimental results indicates the effectiveness of the method. By applying the method, performance estimate for shear wall under rare earthquakes can be conducted by engineering designer, dispense with complicated nonlinear analysis.
