【摘要】:針對我國目前資源短缺、勞動力成本高昂、新型城鎮(zhèn)化進程加快的現(xiàn)狀,建筑業(yè)產(chǎn)業(yè)結(jié)構(gòu)升級的需求日益增加,各地掀起了裝配式混凝土建筑研究及應(yīng)用的熱潮。但目前我國的裝配式混凝土結(jié)構(gòu)建筑仍處于初級發(fā)展階段,相應(yīng)的標準體系尚不完善,制約了裝配式混凝土建筑的發(fā)展,F(xiàn)階段如何完善裝配式混凝土結(jié)構(gòu)建筑的標準體系仍亟待解決,首先就需要對現(xiàn)階段標準體系的適用性進行研究。為此,本文對裝配式混凝土結(jié)構(gòu)建筑標準體系的適用性進行研究,以找出標準體系的合理之處與不適用之處,提高現(xiàn)行標準的科學(xué)性、實用性以及有效性,促進裝配式混凝土結(jié)構(gòu)建筑現(xiàn)行標準的有效實施,為構(gòu)建一個完善、適用的標準體系奠定基礎(chǔ)。本文對我國裝配式建筑標準體系的發(fā)展歷程及各階段標準體系框架進行了梳理及分析,明晰我國現(xiàn)階段裝配式混凝土結(jié)構(gòu)建筑標準體系的現(xiàn)狀,結(jié)合已有文獻研究,分別從標準體系內(nèi)部層面與外部層面對裝配式混凝土結(jié)構(gòu)建筑標準體系適用性進行分析,其中內(nèi)部層面從微觀與宏觀的角度切入分析,外部層面分別從效益性、周期性以及使用性進行分析,并在此基礎(chǔ)上構(gòu)建裝配式混凝土結(jié)構(gòu)建筑標準體系適用性評價模型,運用DEMATEL方法篩選出最終的評價指標。同時結(jié)合本文的研究目的及各評價方法的優(yōu)缺點,選擇基于中心點三角白化權(quán)函數(shù)的灰色聚類評價方法作為本文的評價方法。本文以我國現(xiàn)行的裝配式混凝土建筑標準體系為例,通過咨詢相關(guān)專家及技術(shù)人員的意見將適用性評價對象的水平劃分成若干灰類,并確定各灰類的數(shù)據(jù)范圍,最后將各專家的打分值代入各灰類集合得到綜合聚類系數(shù),根據(jù)隸屬度最大原則判斷裝配式混凝土結(jié)構(gòu)建筑標準體系適用性所屬的灰類。同時根據(jù)評價結(jié)果得出結(jié)論,提出裝配式混凝土結(jié)構(gòu)建筑標準體系完善的建議。
[Abstract]:In view of the shortage of resources, the high labor cost, the accelerated process of new urbanization and the increasing demand for the upgrading of the industrial structure of the construction industry, there has been an upsurge in the research and application of prefabricated concrete buildings in various places. But at present, the prefabricated concrete structure building in our country is still in the primary stage of development, and the corresponding standard system is not perfect, which restricts the development of the prefabricated concrete building. At present, how to perfect the standard system of prefabricated concrete structure is still urgent to be solved. Firstly, it is necessary to study the applicability of the present standard system. Therefore, this paper studies the applicability of the building standard system of prefabricated concrete structure, in order to find out the rationality and inapplicability of the standard system, and to improve the scientific, practical and effective of the current standard. To promote the effective implementation of the existing standards of prefabricated concrete structures, and to lay a foundation for the construction of a perfect and applicable standard system. In this paper, the course of development and the frame of standard system of each stage of prefabricated building standard system in our country are analyzed, and the present situation of building standard system of prefabricated concrete structure in our country is clarified, combined with the research of existing literature. The applicability of the building standard system of prefabricated concrete structure is analyzed from the internal and external levels of the standard system respectively, in which the internal level is analyzed from the micro and macro angle, and the external level from the perspective of efficiency. Based on the analysis of periodicity and serviceability, an evaluation model of the applicability of building standard system for prefabricated concrete structures is constructed, and the final evaluation index is screened by using DEMATEL method. At the same time, according to the purpose of this paper and the advantages and disadvantages of each evaluation method, the grey clustering evaluation method based on center point triangle whitening weight function is selected as the evaluation method of this paper. Taking the present standard system of prefabricated concrete building in China as an example, the level of applicability evaluation object is divided into several ash classes by consulting relevant experts and technicians, and the data range of each ash class is determined. Finally, the scoring value of each expert is substituted into each grey class set to obtain the comprehensive clustering coefficient, and the grey class belonging to the building standard system of assembled concrete structure is judged according to the principle of maximum membership degree. At the same time, according to the result of evaluation, the paper puts forward the suggestion of perfecting the building standard system of prefabricated concrete structure.
