Published: March 2021

Abstract
Mortise and tenon joint is a common connection way of ancient Chinese timber structure. On this basis, in order to explore for a new type of mortise and tenon joint suitable for steel structure, the finite element model of a new type of steel mortise and tenon joint was established to simulate the whole behavior of it under tensile force and bending moment by using ABAQUS software. In this way, the effects of tenon number, tenon height and tenon width on the maximum local Mises stress, area of plastic stress region, tensile and flexural properties were discussed. The results show that the maximum local Mises stress, area of plastic stress region, tensile and flexural properties of the new steel mortise and tenon joint are significantly affected by the tenon number and height, while the tenon width has little effect on these properties. When the tenon number is 4, the tenon height is 15mm, and the tenon width is 5mm, the new steel mortise and tenon joint has the best mechanical performance, and the steel consumption is relatively lower.

Published: March 2021

Abstract
In this paper, the influence of HPMC, which serves as an admixture, on workability, air content, slump loss and compressive strength of concrete is studied in detail based on a blending method. The test results show that the workability of concrete with a 2% admixture containing 0.04% HPMC can meet the construction requirements under the same conditions. Besides, its air content is 2.1% and the compressive strength of it is the highest. However, when the content of HPMC exceeds 0.04% or more, the air content of concrete will be higher and the compressive strength of it will get lower.

Experimental study on self - reset properties of RC beams with different proportions of SMA wires
Authors: Liu Jiarui , Cui Xian 
Published: March 2021

Abstract
In order to explore the influence of SMA concrete beams with different proportions of SMA wires (unidirectional memory and hyperelastic) on the bearing capacity, five SMA concrete beams were made in this experiment. Twelve SMA wires with a diameter of 1mm were placed in the tensile zone of beams, which were reinforced according to different proportions of SMA. The experimental results show that: Within the range of 0-10kN (25% of the ultimate load of beams), the concrete beams with 70% hyperelastic SMA and 30% unidirectional memory SMA has the best stiffness. But in general, the concrete beams with 30% hyperelastic SMA and 70% unidirec-tional memory SMA has the best stiffness; After the first load, the concrete beams strengthened by SMA wires were heated to make the unidirectional memory SMA wires in the beams recover the deformation, and the second load was carried out. The results show that the beams bearing capacity can be improved when the SMA wires recover deformation after heating. The higher the SMA of unidirectional memory, the improvement of load bearing becomes better. However, it is necessary to adjust the proportion of the unidirectional memory SMA wires and the hyperelastic SMA wires to achieve the best effect on the stiffness and resilience of the beam.

Published: March 2021

Abstract
As an effective way to inspect and maintain the shield cutterhead, the safety of the inspection shaft is very important in the process of shield tunneling into the shaft. In this study, numerical analysis was adopted to study the interaction of shaft excavation and shield tunneling process and the response law of stratum deformation. Research shows that during the process of the shield tunnelling into the shaft, the bending moment of the enhanced segment of the shaft has the largest change, followed by the lower part of the regular segment and the shield segment. The smaller the shaft excavation space and the more timely the support, the smaller the ground settlement and influence range. The closer the shield support stress ratio is to 1, the smaller the disturbed area of the stratum. It is suggested that The structure strength, monitoring points and monitoring frequency of the enhanced segment and the lower part of the regular segment need to be strengthened. The construction schedule and safety should be taken into consideration when determining the shaft excavation space and shield support pressure.

Authors: Bin Yu 
Published: March 2021

Abstract
Taking pervious concrete with a target porosity of 15% as the research object, the influence of three factors, including the contents of silica fume (mass fraction3%, 5%, 7%), metakaolin (mass fraction8%, 10%, 12%) and Polypropylene fiber content (volume fraction1%, 2%, 3%), on the mechanical properties, permeability and frost durability of pervious concrete were investigated by utilizing the orthogonal testing method. Through the range analysis of the test results, the significant influence degree of the three factors were obtained, and the freeze-thaw cycle test was carried out with the optimal mix ratio. The results indicated that the content of silica fume and metakaolin has the most significant influence on the mechanical properties of pervious concrete, the fiber has the most significant influence on the continuous porosity, but the influence on the compressive strength is small. The best mix proportion was obtained, and the silica fume content is 7%, metakaolin content is 10%, and fiber content is 2%. The results of freeze-thaw cycle test of pervious concrete with optimal mix ratio show that the relative dynamic modulus and compressive strength of pervious concrete decrease gradually with the increase of freezing-thawing cycles, and the change rate of mass loss, continuous porosity increases gradually with the increase of freeze-thaw cycles. The relative residual compressive strength and dynamic elastic modulus of pervious concrete show a parabolic decline trend subjected to freeze-thaw cycles. The results also can provide technical reference for the engineering application of pervious concrete in cold regions.

Published: March 2021

Abstract
In order to combine the advantages of steel reinforced concrete column, high-strength concrete and precast structures, a new steel reinforced high-strength concrete composite column is presented in this paper. With the aim to explore the post-fire behavior of this composite column under eccentric compression, based on the test results, the commercial finite element software ABAQUS was used to simulate the temperature field and then evaluated that sectional damage. The results indicated that the core temperature of the specimen increases with the increase of the thickness of the protective layer of the section steel, and decreases with the increase of the heating time; the longer the heating time, the more serious the section damage is. Based on the theory of equivalent strength, the reduction coefficient of post-fire strength of concrete was determined. Finally, the calculation method of residual capacity of proposed columns was put forward and verified to be valid.

Published: March 2021

Abstract
Centralised district cooling system equipped with ice storage has substantial advantages in comprehensive energy utilization and cost effectiveness. It facilitates cutting peak and filling valley of power load and helps saving energy costs by using the peak-valley electricity price. Despite such advantages, energy performance of ice-storage district cooling systems is still a controversial topic, especially there is a lack of effective evaluation methods and relevant evaluation standards in China. Therefore, this paper establishes a thorough index system to evaluate energy performance of ice-storage district cooling system. The index system covers all aspects of ice-storage district cooling systems, including the gradual evaluation of each process from equipment, via subsystem to whole system. Afterwards, the index system is used to analyse a real case, focusing on the eight most important energy performance indexes. The results show that the index system can adapt well to the evaluation requirements, help to find energy performance problems and facilitate to improve energy efficiency. In view of existing insufficiency, further efforts are needed to make in formulating reasonable benchmarks of such energy performance indexes.
