Abstract: In this paper, the contents, meaning and importance of conceptual design in the high-rise building structure design are explored from the following respects: structural system, facade layout and multi-channel seismic line. It not only provides a strong protection of concept for calculation of high-rise building structures, but also accumulates some experience for the research on conceptual design of high-rise structures.

Abstract: Based on the tri-axial tests, the stress-strain relationship and strength properties of reinforced expensive soils are studied to get the relation between the strength index of reinforced soil and that of the corresponding plain soil. According to stress-strain relationship of reinforcement soils under different layers and principle of equivalent confining pressure, strength properties of reinforced expensive soils with failure material were analyzed. Mohr circles of different reinforcement layers were tangent to the same line while reinforcement materials fractured. With the increment of axial pressure, different layers were fractured slowly and Mohr circles extended outward. It showed that the strength of reinforcement soils increased with increasing the layers. And the tri-axial tests showed that strength envelopes of reinforcement soils with layers of flexible materials were approximately parallel. The increment of strength was only affected by increment of cohesion.

Abstract: The paper summarizes seven typical moods of the application of glass as a performance material in architecture designing with examples. It points out that glass is not only function material but also performance material in architecture. It also provides a new thought to deal with the glass in architecture designing.

Abstract: The purpose of this paper is to solve issues in current hospital such as complex process, large time-consumption and monotony of space design. The research in the paper introduced the principle of matrix with sections and departments as elements, streamline traffic as transmission path of signals, people seeing doctor as method of signals. Therefore, a fresh model of hospital design was made. The result of the research showed its guiding line for hospital design under the new condition. The unique feature of the research is that design innovation was made in hospital design by integrating of knowledge of different disciplines.

Abstract: The gear pump-motor unity machine, which was composed of the planetary gear pump and multiple gear variable-displacement motor was designed by the author. In this paper, based on the physical model, mathematical models of the machine were established. The transfer functions were deduced and the block diagrams of the transfer functions were drawn. The dynamic characteristics of the machine were analyzed. While the damping coefficient is rising, the oscillation amplitude will decrease. While the damping coefficient is bigger, both overshoot fluctuation are smaller. While the steady-state adjusting time is decreasing, dynamic response characteristics of the motor significantly improved. While the leakage coefficient is rising, the response speed of motor will improve, but the excessive leakage coefficient increases will lead to larger leakage, which seriously impact the motor performance. The dynamic characteristics of the machine were analyzed. As of ωn>0 and ξ>0, gear-pump motor unity machine is inevitably stable.

Abstract: The static strength of circular hollow section (CHS) T-joint reinforced with FRP (Fiber Reinforced Polymer) is studied through the experimental test and finite element simulation. Based on the reliability of the finite element simulation which is verified from experimental data, the parametric analysis is conducted by using finite element (FE) software ABAQUS. In the parametric analysis, the improvement of FRP with different bonding lengths, directions and layers on the static strength of tubular T-joints is considered. Simultaneously, the effect of two key geometrical parameters  and  of the tubular joints on the reinforced efficiency is also included. Based on the results of the parametric study, the effect of FRP on increasing the static strength of tubular joints is finally generalized.

Abstract: In this paper, a theater design tool, “Auto-theater”, tentatively made by the author is proposed to improve the theater design based on the parameter design. In the past, almost all the architects used the tools made by the software manufactures to draw graphics. Now, a few architects start to make the tools by themselves to generate designs. The primary objective is to help the architects focus themselves from using drawing tools onto making their own design tools, so that they will better understand the architectural rules. The paper describes in detail the development of “Auto-theater”, discusses its application and outlooks its future.

Abstract: Shape memory alloy (SMA) is provided with preferable damp capacity at pseudo-elasticity state, applying this property, a SMA re-centring damper is introduced by some scholars. In this paper, the new isolation system combining the above damper with laminated rubber bearing is proposed, so as to obtain preferable isolation character and re-centring capacity. To illustrate the feasibility and effectiveness of the proposed system, the following work is done: First, according the constitution model of SMA at pseudo-elasticity state the program is compiled, then the mechanical behavior of damper is simulated and the hysteretic curve is obtained. Based on the above, a linear restoring model for SMA re-centring damper is put forward. And then, the program based on the theory of story model for shear tape is compiled to conduct elasto-plastic time history analysis of practical structure examples, According to the results, the seismic response of structure is significantly reduced, and the fully re-centring capacity after earthquake is obtained by this isolation system.

Abstract: Through the discourse about basic concepts, principles and methods of vernacular ecological architecture, construct a basic theoretical framework on architectural design and natural ecological environment. From the combination of theory and practice, clarify the design ideas of local ecological architecture and sustainable development thinking in Chinese traditional culture. To analyze ecological character of dike folk houses in Southeast Henan, reflect on and answer the important significance of sustainable development in the new rural construction.
