In the operation stage, current green buildings gradually take energy conservation into consideration, a trend resulting in a phenomenon that environmental control system neglects suitability of indoor personnel. This article summarizes the advantages and disadvantages of several existing indoor thermal comfortability evaluation indicators by selectively analyzing common factors that affect personnel satisfaction, including personnel factors, indoor environmental factors, space factors, design factors, equipment factors, construction and property factors, and work factors. By combining the questionnaire to screen first-level impact factors, this article provides a basis for exploring a new multi-method-based evaluation method of intersection satisfaction.

During the operation phase, energy conservation of buildings gets much attention. controlling methods are often based on physical parameters, ignoring the specific needs of different groups of people for the environment. To evaluate the current status, the questionnaire is used to investigate the relationship between personnel comfortability and various factors. This article aims to introduce the method of personnel portraits, balance the personality and common conflicts of the crowd, and solve the control problem of comfort that varies from person to person. Finally, combined with the analysis of the results of the questionnaire, a multi-faceted study of personnel satisfaction was provided to provide a reference for methods that can achieve energy-saving and satisfaction control at the same time.

Due to increasingly complex structures and higher prefabrication rates, the hoisting order of precast components in fabricated buildings is gradually getting attention. During the assembly construction forbidding precast components on site, there are some influencing factors that interfere with the smooth implementation of a hoisting sequence scheme. This paper identifies and analyzes these factors through literature method, on-site investigation, and expert interview to establish an index system affecting the changes of a hoisting sequence scheme. Then, the index system is illustrated through a case, and the results show that the changes of a hoisting sequence scheme caused by transportation management are more than those caused by construction site management. Finally, this paper also discusses some influencing factors that affecting the changes of a hoisting sequence scheme in the premise of allowing precast components to be stacked on site. © 2018 American Society of Civil Engineers.

Six specimens of concrete frame columns reinforced by post-build wing walls on the opposite faces were designed and fabricated to investigate their seismic performance. Axial compression ratio was considered as the critical factor and divided into 0.31, 0.36, and 0.40 before reinforcement. HRB400 steel grade was used to the longitudinal bar and the ratio of longitudinal reinforcement divided into 1.23%, 1.05% and 0.82%, stirrup reinforcement ratio was 0.6%, and the stirrups were made by HPB300 steel grade. To meet with requirement of ‘strong shear, weak bending’, the ratio of the shear span to effective depth of columns was equal to 2.4. All specimens were subjected into cyclic reversing load. The testing results showed that wing walls reinforced significantly increased the seismic bearing capacity of the specimens and the wing walls damaged seriously, but the columns were not. The limited drift was ranged from 0.021 to 0.033. The post-build wing walls under horizontal motion may dissipate energy effectively while ensuring that the existing columns without obvious damage under vertical loads and earthquake strong motion. © Fan and Ying;Licensee Bentham Open.

Building information modeling (BIM) is regarded as a feasible and efficient tool to realize sustainable construction. A lot of research has been conducted using BIM to evaluate and improve environmental, economic, and social performance of construction. Yet there is still lacking in a review which analyzes the application of BIM in sustainable construction (ABSC). This study utilized a systematic literature searching-selection-classifying method to obtain papers of ABSC research from five databases. To investigate who contributes most in ABSC field, the papers were distributed according to the countries/regions, journals, and research centers. To reveal the research emphasis and research trend in ABSC field, the emphasis of research level, project phase, sustainable dimension, and research topic was analyzed. Based on the analysis results, four critical gaps of ABSC research have been identified, including a lack of an integrated BIM tool for all three sustainable dimensions, unexplored potential of BIM in infrastructure, a lack of sustainable BIM application for maintenance and operation management, and a lack of sustainable BIM application at organizational level. This study will be valuable for researchers to gain an in-depth understanding of research trend and knowledge gaps in ABSC research, and future studies could be conducted to fill the gaps found in this review. © 2018 American Society of Civil Engineers.

The last decades have witness the rapid urbanization in china, which cause the growing demand for affordable housing. Meanwhile, many social and environmental problems arise due to the large-scale rural-urban migration, which attract attention of the government and the public. Comparing with traditional one-site construction, prefabricated construction is more environmentally friendly and labor-saving, exactly meeting the current demand in china. To promote the application of prefabricated construction in the field of affordable housing construction and the sustainable degree of affordable housing construction, this paper first analyzes the relevance and similar characters between prefabricated buildings and affordable housing construction. We further states that prefabricated buildings play a facilitative role in the construction of affordable housing and how affordable housing construction feeds back prefabricated buildings. On this basis, we analyze how to realize the sustainability of affordable housing and put forward a conceptual framework of sustainable affordable housing. © 2018 American Society of Civil Engineers.

Safety uncertainties widely exist in every phase of construction projects, especially during the on-site building stage. To identify different kinds of on-site safety uncertainties, a four-level analytic hierarchy process (AHP) model is proposed based on china's current construction industry standards. Then analyze the influence and frequency of level-4th (L4) factors, synthesized cloud model (SCM) is applied to sampling calculation program, with which both randomness and fuzziness can be jointly considered. Finally, a multi-factor assessment method (MAM) under fuzzy sets theory is used to assess level-3rd (L3), level-2nd (L2), and level-1st (L1) factors of on-site safety system. Such methodology not only avoids the limitation of filling in huge numbers of written documents, but also can realize the dynamic adjustment of system factors, and may significantly decrease the difficulty of on-site safety management and safety inspection. In addition, practical advices are put forward to avoid some limitations of standard. © 2018 American Society of Civil Engineers.

Prefabricated shear walls are currently widely applied in mid-to-high-rise structures. As a new type of structural form of assembled shear walls, the ring connection assembled concrete shear wall has clear mechanical mechanism, easy construction and better performance and other significant advantages, which are gradually being applied in actual engineering. However, few systematic studies are carried on this new type of shear wall structure, and a complete theoretical system for guiding the design could not be given, especially in terms of mechanical mechanism and seismic performance, more detailed research work is needed. This paper uses numerical simulation as the main method to study the influence of different design variables such as shear span ratio, buckle size, axial compression ratio on the mechanical properties of the connection area in shear wall and the overall seismic performance of the structure. In this way, the theoretical basis for further optimizing the structural performance of the shear wall connection with ring connection.

Earthquake Engineering and Engineering Vibration 2017年第4期16卷 859-881页

作者： Zhai Changhai Wang Xiaomin Kong Jingchang Li Shuang Xie Lili School of Civil Engineering Harbin Institute of TechnologyHarbin 150090China Key Lab of Structures Dynamic Behavior and Control(Harbin Institute of Technology) Ministry of EducationHeilongjiangHarbin 150090China Institute of Engineering Mechanics China Earthquake AdministrationHarbin 150080China

The development of a powerful numerical model to simulate the fracture behavior of concrete material has long been one of the dominant research areas in earthquake engineering. A reliable model should be able to adequately represent the discontinuous characteristics of cracks and simulate various failure behaviors under complicated loading conditions. In this paper, a numerical formulation, which incorporates a sophisticated rigid-plastic interface constitutive model coupling cohesion softening, contact, friction and shear dilatation into the XFEM, is proposed to describe various crack behaviors of concrete material. An effective numerical integration scheme for accurately assembling the contribution to the weak form on both sides of the discontinuity is introduced. The effectiveness of the proposed method has been assessed by simulating several well-known experimental tests. It is concluded that the numerical method can successfully capture the crack paths and accurately predict the fracture behavior of concrete structures. The influence ofmode-Ⅱ parameters on the mixed-mode fracture behavior is further investigated to better determine these parameters.
