Purpose The construction industry is characterized by a long construction period, high cost and many uncontrollable factors. The owners and contractors are increasingly focusing on the efficiency of their construction and costs in pursuit of greater economic benefits. However, current methods used in the construction period and cost optimization analysis with multiple constraints the have their own limitations. Therefore, this study aims to propose a combination of genetic algorithm (GA) and building information modeling (BIM) to construct a five-dimensional construction duration-cost optimization model with the advantages of optimization and simulation for optimization. Design/methodology/approach This design first analyzed the characteristics of changing construction period and cost and then improved the genetic mechanism and the data processing method in the GA according to the aforementioned characteristics. Then, BIM technology was combined with GA to testify the feasibility of the model in the practical engineering project. Findings The result proved that this new method was reasonable and effective in dealing with the complicated problem of period and cost. GA accelerated the optimization process and yielded a reliable Pareto solution. BIM technology simulated the construction process before construction to increase the feasibility of the construction scheme. Originality/value This method not only can rapidly provide the best construction period/cost decision to the architect according to the previous working period/cost or contract data that can meet the demands of the architect but also visualize the construction and give a dynamic schedule of the project.

Impact loads from the crash of automobile always challenge the structural parts of the collided vehicles. Modern high – speed vehicles are subjected to high impact loads during accidents when the vehicle is accelerating at high speeds. This results in structural damage to the vehicle as well as passengers in the vehicle. In recent years, high-strength aluminum alloys have increasingly been used for building high-speed vehicles, and other types of weight-critical structures. In such structures, stiffened panels are the basic strength members. Composite panels can be used for the car body to reduce the weight of the vehicle and to increase the collision resistance. In this study, the aluminum composite panels with composite filled stiffeners are fabricated and tested experimentally under compression and impact loadings. Recycled ceramic powder, recycled steel flakes, and E - glass fiber mesh is taken as reinforcements and thermoplastic resins as matrix materials in the preparation stiffener filler composite. The composite panel specimens are fabricated and are tested experimentally under axial compression for collapse resistance.

Initial Setting

the construction method of the ordinary cemented soil stiffness core composite pile is that the pile peripheral cemented soil and the core pile are constructed at different time, which might lead to the situations as the pile body is broken due to the forced inserting of the core pile into the cemented soil mixed pile after the initial setting time, the neighboring finished pile is damaged due to the compacting effect caused by the reaming construction of the core pile and the failure of effectively transferring the load due to the loose joining of stiffness core pile and the cemented soil whose construction is completed after the initial setting time. This paper aims to overcome the defects of the conventional construction method by introducing a new construction technology, and the construction technology is verified to be reliable through the application in the actual engineering projects and has the advantages that the peripheral soil body is significantly strengthened, the composite pile foundation can effectively overcome the harm as uneven settlement of buildings, so as to ensure the normal usage of the buildings, and the construction technology has excellent economic benefits and is significant for the later construction technology for treating the soft soil foundation.

Rubber dam is a type of soft shell hydraulic structure, which is rechargeable and scalable. Relative to other hydraulic structure that has the same function, rubber dam has many advantages, low cost, short construction period, simple to operation and maintenance, and long service life. Rubber dam is now widely used in industrial and agricultural production, which have improved the ecological environment and cityscape. The Fuqing River, whose water is stench, dirty, have been seriously affecting the city appearance. This paper discusses on construction three-level cascade rubber dam in the Fuqing River to improve the water quality. Build those rubber dams project on the Fuqing River, which not only improve the water quality, beautify the environment, improve the urban ecological environment, create good environment for residents living, can also create social and economic benefits.

Abstract It is of great significance to improve the mechanization level and construction quality of tunnel construction. At present, large cross-section tunnels are emerging in China. The construction method based on manual work and supplemented by a machinery has long construction period, high labor intensity, and structural quality that cannot be guaranteed. To address those issues, this paper proposes the construction method of bolting-grouting integrated operation for an unmanned arch erection to achieve the rapid and safe construction of large section tunnels and reducing the amount of manual work. This paper mainly introduces the bolting-grouting integrated operation trolley, which can achieve the automatic installation of steel arch, the construction of locking anchor pipe, and shotcrete. Besides, this paper designs a new type of steel arch and an alternative way of longitudinal connecting reinforcement of steel arch. Moreover, with the field test and optimization adjustment of the Xinwushaoling tunnel, it is found that the construction method of bolting-grouting integrated operation for unmanned arch erection can overcome some disadvantages of traditional construction methods.
