Starting from cultural roots, the paper fully explores traditional Chinese culture and clearly defines the definition, connotation as well as features of Chinese cultural tradition. As the carrier of Chinese culture, Chinese traditional architecture emphasizes natural landscape and expresses the concepts of "oneness of nature and man", which are consistent with the modern desire of "living in nature". Through studying distribution features, ecological characteristics and building experience of Chinese traditional architecture, combining related practices of building a green city in recent years, and based on the research of traditional culture on design of cities, we plan to promote the organic development of green city. The paper takes Hankou town for example. The examples receive inspiration from the ecological concept of traditional architecture, and put into practice the ecological concept under guidance of culture. Modern architectural language and green technology are used to interpret traditional architectural features. We will better promote the organic development of green city through fully exploring and inheriting culture. © 2017 Published by Elsevier Ltd.

The paper takes design of the tenth China (Wuhan) International Garden EXPO as an example, concludes the development direction of low-carbon parks in China, and highlights the use of sponge city and green architecture design. Firstly, the paper introduces overview and design cases of the EXPO. Then, the paper elaborates the goals of low-carbon design. It describes the low-carbon technical application of the EXPO park, i.e. comprehensive design based on overall coordination and avoidance of conflicts, intelligent city planning, processing technology of existing landfill, conducting onsite balance work for earthwork, water recycling system planning, building ecological low-carbon architecture, building and repairing of ecological darning bridge, etc. Besides, the park also adopts design principle of sponge city. As an urban oasis, Wuhan International Garden EXPO darns the divided city; as a public space, it provides an ecological space for more citizens to visit and enjoy. Its example is a reference for design of low-carbon parks in China in the future. © 2017 The Authors. Published.

This paper presents an experimental investigation on two full-scale tension-only concentrically braced beam-through frames (TOCBBTFs) with through beam bolted connections. This type of TOCBBTF system features cold-formed square-tube section columns connected to H-section through beams by bolted end plate. It is commonly used in low-rise prefabricated buildings. Two two-story, four-span by one-span TOCBBTFs subjected to design vertical load were cyclically loaded horizontally to examine the seismic behavior. Stable behavior was observed up to a story drift angle of 1/10. The cyclic behavior was characterized by a linear response, followed by a slip range and a significant hardening response. Deteriorating pinched hysteresis was observed due to the occurrence of cyclic brace compression buckling and tension yielding. The structural damage evolution, ductility, stiffness and shear force distribution of the TOCBBTFs were investigated. Moreover, the finite element software ABAQUS was used to investigate the behavior of TOCBBTF by nonlinear analysis. Semi-rigid analysis produced the most reasonable prediction including initial lateral stiffness and peak story shear. The calibrated numerical models can be employed to launch further studies for this structural system. © 2012 Elsevier Ltd. All rights reserved.

Damage such as cable pre-stress loss and anchorage failure may occur in a glass curtain wall structure supported by single-layer plane cable net but the influence on overall structural responses has not yet been identified. A finiteelement model considering the stiffness contribution from glass panels is established to study the effects of two forms of damage: pre-stress loss and anchorage failure. The accuracy and reliability of the numerical model are validated experimentally, and the effects of stiffness of the glass panel on stress distributions are discussed. Compared to experimental results, the finite-element model has sufficient accuracy to quantify the damage effects. The contribution from bending stiffness of glass panels to overall structural stiffness is identified as about 10.6% and that from the glass panel membrane effect is about 12.2%. The modelling approach is extended to describe a realistic 15 × 3 15 m glass curtain wall structure. The corresponding parametric analysis demonstrates that the stiffness contribution from glass panels depends on certain design parameters (e.g. number of glass grids and overall span), but can be ignored for structures with more than ten grids. In the investigated structures with 6~15 grids, almost no difference was found between the effects of damage on the glass curtain wall structure and on the pure supporting cable net structure. © ICE Publishing: All rights reserved.

It is one of the keys that determining reasonable damping block geometry in the process of designing the extrusion dies. In this paper, the finite element software POLYFLOW was used to simulate the flow process of tread rubber in the head channel. In addition, the orthogonal experiment method was adopted for the optimum design of the damping block in the head channel. After optimum design, the flow velocity of rubber melt becomes more uniform in the full width at the head outlet. Consequently, the warping deformation of the rubber, which flow through the head channel, is also significantly reduced. © (2014) Trans Tech Publications, Switzerland.

Structures subjected to violent ground shaking may be left in a displaced condition. This residual or permanent displacement may render the structures unsafe or irreparable. This paper presents the results of a parametric study aimed to construct the constant-ductility Residual Displacement Ratio (RDR) response spectrum of bilinear Single- Degree-of-Freedom (SDOF) systems subjected to strong earthquake ground motions. The RDRs, which are defined as the ratios between the residual displacement and the yield displacement, were computed using nonlinear time history analyses of bilinear SDOF systems subjected to 100 scaled ground motions. The results were statistically organized to establish the constant-ductility RDR response spectrum. © 2016 Taylor & Francis Group, London.

The structural configuration and method of analysis of the single-layer inverted catenary cylindrical reticulated shell are introduced in this paper, and the elastic as well as elastic-plastic stability of this kind of reticulated shell is then investigated. The stability of the structures with different types of grid patterns is compared, and the reasonable grid pattern is hence recommended. The structural buckling mode and ultimate load-carrying capacity are studied in detail by parametric analysis. Influence of various factors on structural ultimate load is investigated, and the fitting formula of ultimate load is thus presented. Comparison analysis between the inverted catenary and circular cylindrical reticulated shells is also carried out. The work will provide guidance in theory for practical applications of this kind of structure. © 2014 Elsevier Ltd.

In order to enhance the performance of phosphorous (P) adsorption onto bamboo charcoal (BC), a novel aluminum modified bamboo charcoal (Al-BC) was fabricated with aluminum chloride solution by aluminum salt hydrolysis coprecipitation method. The physicochemical properties before and after modified bamboo charcoal were determined. And the characteristics of P adsorption onto Al-BC and BC were investigated in batch tests. The results show that the P adsorption process can be described well as Freundlich and Langmuir isotherms, and Freundlich equation is better fitted than Langmuir equation. Adsorption capacity of Al-BC is 10.0 mg·g-1, which is about 1.3 times that of BC. The adsorption well follows Lagergren-second order models. The effect of pH on P adsorption is distinct and the acidic conditions are favor for P adsorption. Humid acid has obviously negative influence on P adsorption, while NO3-has no obvious inhibitory effect on P adsorption. © 2015, Huazhong University of Science and Technology. All right reserved.

A vertical U-tube ground heat exchanger can be utilized to exchange heat with the soil in ground source heat pump systems. The outlet temperature of the working fluid through the U-tube is an important characteristic parameter of heat transfer process. It is quantified by an effectiveness coefficient of ground heat exchanger in this paper. A multipole model based upon the multipole theory is developed inside the borehole with a cylindrical heat source outside the borehole, considering the working fluid temperature variety along the U-tube and its heat convection. The model overcomes the boundary shape limitation of traditional analytic model and could analyze the temperature field in complex profile and boundary, such as the two branch pipes of GHE. The experimental validation of the multipole model has been performed. A dynamic simulation was conducted to evaluate the influence of a number of parameters on thermal effectiveness. The effect of some important characteristic factors on the heat transfer performance of ground heat exchangers is analyzed. The results may provide the references for design of ground source heat pump system in actual projects. © 2013 Elsevier B.V. All rights reserved.

Make an analysis and points out that the engineering conditions of variable speed working condition of water pump in line with the proportionality law are as follows: non-back-pressure system, all parallel pumps changing speed synchronously(including a single variable speed pump system) and fixed pipeline characteristic curve. Energy saving effect analysis of variable speed pumps should be based on the energy consumption comparison of the pump variable speed control to other flow control methods in conditions of achieving the same flow, but not to the design working condition. © (2013) Trans Tech Publications, Switzerland.
