Abstract ：
There are obvious differences in shape and space between the large-span spatial structure and the traditional steel structure, and there will be openings at the top of the spatial structure. However, there are few studies on the fire of the spherical dome large space building with openings at the top, which makes the classical plume model inapplicable. The axial temperature of the plume centerline predicted by the traditional plume model is quite different from the real results. Therefore, this paper investigates the temperature dynamics within large-span spatial structures during large-scale fire scenarios, utilizing a combination of theoretical analysis and finite element numerical simulations. It meticulously assesses how different natural ventilation inlet areas affect both the smoke exhaust capacity and the temperature field distribution within these structures. The research expands on the traditional plume model by introducing an enhanced formula for calculating the plume center velocity, specifically designed for large-span structures with top openings. Additionally, using an improved two-region model, the paper derives a logarithmic model that describes the temperature variation as a function of vertical height within the structure. This theoretical model is then compared with numerical simulation results. The study finds that increasing the natural ventilation inlet area significantly enhances the efficiency of smoke exhaust and reduces temperatures within the fire smoke layer of large-span spatial structures. The derived temperature logarithmic curve model shows high precision in predicting the spatial temperature distribution after the fire reaches a quasi-steady state, with an average relative error of 6% between predicted and simulated temperatures, confirming its accuracy. The conclusion is of great significance to the study of fire smoke movement in large-span spatial structures. The obtained logarithmic curve model of temperature under fire provides an important basis for the fire protection design of spherical dome spatial structures under natural smoke exhaust.

Abstract ：
In order to avoid the instability of compression support in annular space cable truss structures, a novel full-tension crossed cable-truss structure (FCCTS) is studied. Firstly, according to the geometric shape of cables, the distribution law of cable force in the pre-stressed state is deduced and analyzed by theory. According to the characteristics of the cable force of vertical cables being much smaller than that of upper and lower chord cables, a forming method of tensioning vertical cables, namely, the vertical cable-shortening method (VSM), is proposed. Corresponding node connection devices are also designed and tested. Subsequently, the VSM process for establishing tension is elaborated in detail, and its feasibility is numerically simulated and validated. The results clearly show that VSM can effectively establish the pre-stress state in FCCTS. The VSM has the advantage of low applied tension, making it easier to form structural tension.

Abstract ：
With the gradual advancement of the country's environmental protection policies, the air-supported membrane structure, characterized by its short construction period, cost-effectiveness, and high safety during construction, has been widely used in the full enclosure renovation of open-air coal yards in coal-fired power plants, the construction of all-weather sports venues, logistics and warehousing, and has gradually entered a large-scale construction phase. The widespread application of air-supported membrane structures has placed higher demands on their operation, maintenance, and scientific monitoring. Taking a coal shed at a power plant in Hengshui city as an example, this article proposes the use of drones equipped with high-precision scanners to scan existing air-supported membrane structures and establish models. This method reduces the differences between the computational analysis model and the actual structure, enhancing the accuracy and reliability of the computational analysis results, thus providing support for the safe operation and maintenance of existing air-supported membrane structures.

Abstract ：
Spatial cable-truss structure without inner ring cables (SCSWIRC) belongs to tensile structure, which is composed of three kinds of cable, strut and stiff ring-beam, and its stiffness generates from the pre-stresses of cables. The manufacturing errors of the three kinds of components determine the final formed state and ultimate bearing capacity, so it is essential to study the influences of manufacturing errors of three kinds of components on the mechanical property of structure. The influences of manufacturing errors on SCSWIRC have been studied from four aspects that include elongation or shortening of cable and strut, different pre-stresses states, different cable-truss frames and external loads. The relations of manufacturing errors and four aspects have been studied based on finite element model and experimental model. The results show that the elongation and shortening of components has little influence on sensitive indexes of components when the elongation or shortening of components is the same. The manufacturing errors have the different influences on the mechanical property of structure under the different pre-stress states. The closer cable-truss frame is to the error position, the larger influence the error has on cable-truss frame. The external loads have not changed the basic mechanical property of SCSWIRC, but the external loads make upper chord cables easier to loose and make sensitive indexes change more greatly. The research contents reveal the influences of manufacturing errors on the mechanical property of SCSWIRC from the four aspects.Copyright (c) 2023 by The Hong Kong Institute of Steel Construction.

Abstract ：
Current suspen-domes use loop cables which are key elements and carry large tensions. Loop-free suspen-dome was proposed for improving the collapse resistance and reducing cable tensions. The collapse resistance of loop-free suspen-dome has not been verified. In this paper, analysis on dynamic response of both current suspen-dome and loop-free suspen-dome induced by sudden cable or strut failure is performed to investigate the collapse resistance. Under the loaded state, cables or struts were suddenly removed from the structure to simulate cables or struts failure. Th residual bearing capacity of the structure after the rupture was also analyzed. It is concluded that collapse resistance of the loop-free suspen-dome is good. Failure mode of the loop-free suspen-dome is proportionate. The effect on the loop-free suspen-dome due to initial failure grows proportionately along with the quantity of failed members. It also turns out that cables in the loop-free suspen-dome are relatively independent. Only the failed cable loses tension, other cables still remain in tension. It is also found that the most important cable or strut in the loop-free suspen-dome is in the outermost layer of the cable-strut system. More concern should be shown to the cables and struts in the outermost layer.

Abstract ：
Cable-truss tensile structures are one of the most imperative types of spatial structures, and a spatial cable-truss structure without inner ring cables (SCSWIRC) is a new type of cable-truss tensile structure. Although SCSWIRC has a strong anti -collapse capacity, its construction forming is difficult. Based on the concept of grid-jumped layout for struts, the experimental model with a span of 6 m is designed, and then three grid-jumped layout schemes are proposed to simplify structure system. The static and dynamic properties of experimental and finite element models are systematically studied. The results show that experimental values agree with simulation values. The errors of the static experiment are in the range of 6%similar to 11.53% and the errors of the dynamic experiment are in the range of 5%similar to 8%. The grid-jumped layout has negligible effects on the internal forces of cables. However, it has excellent effects on the internal forces of struts and nodal displacements at the grid-jumped layout, so the mechanical property of struts needs to be rechecked after grid-jumped layout. The mechanical property of the optimal grid-jumped layout scheme does not change compared with original scheme. The optimal grid-jumped layout scheme not only simplifies SCSWIRC, but also reduces the amount of steel. The study can promote the application of SCSWIRC in practical engineering.

Abstract ：
为研究环形交叉索桁结构(ACCTS)的施工关键技术,利用ANSYS有限元软件建立了直径为100 m的ACCTS有限元模型.基于此模型,研究了环梁刚度、支撑柱形式、温度作用、构件制作温度误差对ACCTS的影响;分析了环梁-支撑柱对ACCTS动力性能的影响.此外,基于可靠度理论及非线性规划理论,提出了索长误差限值计算方法并给出了索长误差控制限值.研究结果表明:在一定范围内提高环梁刚度能够有效降低环梁变形,但超出该范围后其作用不明显;通过环梁预调值法可使调整后的环梁处于设计位形,消除了环梁变形对索力的影响,预调后所得预应力与初始预应力之间的误差范围为0.51%～1.12%,满足工程要求;支撑柱两端的...
