Abstract:
It has been already 10 years since BIM technology was used in the construction of venues for the Beijing Olympic Games.Although BIM technology has been vigorously promoted by the government and widely publicized by the industry, there were merely fewer than 5000 construction projects (about 6‰ of all projects) in 2018 adopted the BIM technology.Following the concept of business process reengineering, this paper reviews the development of BIM technology in construction industry by using OKR model and combing BIM technology from the source.At last, according to the review results, the direction and suggestions for further research on BIM technology are put forward for the future consideration and research.

Abstract:
Hospital buildings are considered to be the most challenging building facilities, and there are many uncertainties in the construction process, such as population trends, disease patterns, technological advances and clinical knowledge.Among them, the safety of buildings in the event of disasters is particularly important.The complexity, density and flammable materials of hospital buildings add to the fire hazard.In the event of fire, due to the differences in evacuation conditions of different personnel, It is very difficult to evacuate, so it is necessary to have possible fire hazards in hospital buildings and to establish comprehensive and reliable fire supervision.This paper describes in detail the technical route of building fire simulation and escape analysis in large hospitals, including model construction, ventilation analysis, fire simulation and evacuation analysis.The simulation analysis is carried out by taking a large hospital as an example to obtain the most unfavorable ventilation conditions.The results of temperature distribution cloud map, smoke distribution cloud map and evacuation route of each room in the fire process can provide technical route reference for the analysis of similar projects through project research.

Abstract:
Structures are often subjected to multiple earthquakes.However, at present, the domestic seismic design specifications in China always consider the impact of single earthquake event, and ignore the response of the bridge structure under the action with multiple earthquakes.In view of this, the authors take the Qiumohe River Bridge as a case study example, to conduct numerical simulation of traditional and cumulative incremental dynamic analysis (IDA) of hollow pier circular end of railway bridge by using the seismic analysis software, OpenSees.The influence of multiple ground motions is studied by comparing displacement responses in two cases.The results show that:(1)The round-ended hollow pier of the railway is soft and the high-order vibration mode is obvious.The maximum displacement and residual displacement of the structure increase with the increase of the peak acceleration.(2)Compared with the single earthquake, the maximum displacement and residual displacement of the structure are both larger with multiple earthquakes.(3)There are two different analysis methods for the maximum displacement response of the structure.When the structure is in an elastic state, the difference is not obvious; and when the structure is in the elastoplastic state, the difference is not negligible.However, for residual displacement, the difference is obvious and cannot be ignored.

Abstract:
Due to the particularity of its structure, once a fire occurs, the subway stations often cause significant casualties and property losses.It is of great significance to study the fire risk assessment of subway stations.Based on the variable analysis of the fire risk grade, this paper establishes an evaluation index system and a hierarchical evaluation structure for the fire risk grade, and also proposes the choice evaluation set to quantify the proposed evaluation index.The project of Metro Line 1 in Nanning, Guangxi Province is taken as an engineering case study to implement the Fuzzy Comprehensive AHP evaluation of fire risk level.The research results show that the fuzzy comprehensive AHP evaluation method is able to comprehensively evaluate the risk grade of station fire through the establishment of comprehensive evaluation index system, which is also able to comprehensively consider the factors that affect the risk grade of the subway station fire.
