摘要：
In order to study the accumulative damage laws on the jointed rock mass under the impact of cyclic and dynamic loading, one to three specimens, including layered and jointed rock mass, were precast separately, which are made of cement-mortar used as similar material. Ultrasonic wave velocity of each specimen could be measured every time by conducting shock loading one to five times separately. On the basis of ultrasonic wave velocity, the damage variable of the specimen is defined. Meanwhile, both the effect of shock damage degree on rock mass under the shock frequency and sets of joint could be obtained. The results show that under the same shock energy, the damage degree is closely related to sets of joint and shock frequency. In addition, when the shock frequency was small, the specimen only produced microcracks and gradually formed macro-destruction with the increase of accumulative shock frequency.

摘要：
The chiller system in a building accounts for the main part of the building's total energy consumption, so it is critical to optimize the operation of chiller system for the purpose of saving energy. A chiller system generally consists of evaporation side and condensing side. The condensing side includes chillers, cooling water pumps and cooling towers, which form a subsystem of cooling water. It is a typical optimization problem to minimize the total energy consumption of cooling water subsystem. This paper discusses how to solve the optimization problem of the cooling water subsystem and proposes a simple optimal control rule for field operation based on the optimization results.
摘要：
In order to study the stress distribution and development of the empty pulp defects in anchor bolts, we carried out an experiment on an empty pulp defective bolt. The dynamic testing signals were obtained by non-destructive testing, and test signals under different loads were analyzed. Research shows that in the defective bolt, the strain and load show a linear trend before the empty pulp defect. In the empty pulp defective section, the strain will not have obvious change until the load reaches a certain value. After the empty pulp defect, stress redistribution occurs with the increase of load.

摘要：
In this paper, Simulink model is built to simulate the chilled water system of a real building. The optimal chilled water flow rate and chilled water supply temperature are found out by traversing the constrained parameter values under different working conditions. The simple optimal control rules are developed based on the optimal solutions. Optimal control rules can reduce the total energy consumption of the chillers, chilled water pumps, and air handling units by 17.55% compared with tradition control.

The Soft Soil excavations;Steel soil-cement mixing pile;Pile combined with slab;ABAQUS: Deformation monitoring
摘要：
In this paper, based on the case of a soft soil excavations project in Zhongshan and the field measured data, the ABAQUS, a finite element software for engineering simulation, analyses the system which combines steel cement-soil pile and basement plate. Moreover it can simulate the deformation results and get the supporting stress model. The results show that the supporting effect of this system is remarkable. This simplified model calculation results are conservative. But there exists the problem of varying depth of excavations. As a result, the stress characteristics and design methods of the proposed scheme are less studied and need further research and discussion. The analysis method and the design scheme can provide useful reference for similar projects.

Green building;post occupantion evaluation;energy performance;cooling/heating source;control strategy optimization
摘要：
With the rapid development of green building, it is important to check the energy and environmental performance of the green building post occupation. This paper focuses on how to evaluate the energy performance of a green building's cooling/heating source of the air-conditioning system post occupation. The operation of the cooling/heating system is checked to find out the problems and optimal control strategy is proposed. The performance of proposed control strategy is verified by simulation and experiments. Simulation analysis confirms that the proposed control strategy can save 21.3% of the heating energy under the condition of satisfying the indoor temperature requirement. Experiments carried out in the building show that the experiment day's heating energy was saved by 19.5% compared to the comparison day, and the total electricity consumption of the cooling/heating source system was saved by 27.4%.

barite concrete;particle flow code in two dimensions;numerical simulation;strain rate;failure mode
摘要：
A meso-scale discrete element model(DEM) of barite concrete beam was developed by the aid of DEM software PFC2D. Using this model, numerical simulations of the test conditions in meso-scale were conducted as well. The dynamic failure process of barite concrete was simulated by changing the quality and drop height of the hammer under the condition of strain rates ranging from 1.4s(-1) to 4.0s(-1), which got the curve of force histories, vertical deflection histories and strain histories. The results of simulation match well with the measurements, thus the model is validated experimentally. Compared with the failure mode at low strain rates, the failure mode at high strain rates suggests that the occurrence of more cracks is the key factor for the strain-rate effects in concrete.

摘要：
The large space industrial building as the research object, established a two-dimensional physical model, using the CFD numerical simulation software simulate the partition effect that an air curtain to indoor pollutants, and analyzed the different exhaust form and air curtain's parameters such as the width, air supply velocity to the influence of the partition effect that an air curtain to indoor pollutions. The results show that the appropriate air curtain's width and air supply velocity will play the important role of good partition to indoor pollutants. When the width of the air curtain is too narrow, it will not good for the partition effect, but when the width is too wide, it is not economic; on the other hand, when the velocity of the air curtain is too big or too small, it also can't have better partition effect. From the perspective of indoor environment protection and energy saving, the air curtain is used in the indoor environment control and research out of the optimal parameters of an air curtain for good partition effect will be of great significance.

摘要：
Based on the exergy analysis model and the data of an ASHPWH system, exergy analysis of the system was carried out, and the way was discussed to reduce exergy loss. The exergy efficiency of the system was 43.7%, and the exergy loss coefficient of the compressor was the largest in the system, accounting for 26.12%. then, the exergy loss coefficient of the expansion valve, the condenser and the evaporator account for 14.15%, 9.82% and 6.21% respectively. The key components to improve the exergy efficiency were compressor and expansion valve, and the join control of electronic expansion valve and variable frequency compressor may be a feasible way to improve improve exergy efficiency.

摘要：
Taking an office building in Changsha city, Hunan Province as the research object, its all-year hourly dynamic load is simulated by EnergyPlus software. On this basis, a simulation model of U-tube ground heat exchangers is built with the GSHP design software of GLD2012. The heat balance problem of the ground source heat pump (GHSP) system in long-term operation is discussed from influencing factors of soil thermophysical parameters and backfill materials' thermal conductivity. The simulation results are analyzed to show the reference to the optimal design of the U-tube ground heat exchanger system in engineering practice.
