Abstract ：
为了简化结构火场温度边界条件，实现FDS火场模拟与后续的结构传热分析和热力耦合分析的无缝衔接，提出利用人工神经网络技术建立大空间火灾温度场预测分析模型的方法.根据大空间结构以及BP网络的特点，首先运用FDS分析大空间结构火灾场景；其次选择坐标和时间4个参数为输入向量，以火场温度为输出向量，建立BP神经网络模型；然后以FDS火灾模拟温度数据为样本，对网络模型进行训练和预测，建立大空间BP神经网络火灾温度场分析模型.结果表明，采用3层人工神经网络模型可以较好预测大空间结构的火灾温度场，预测结果温度场空间分布的相对误差在15%以内，温度场时程分析的相对误差在10%.

Abstract ：
双钢管混凝土复合柱在普通钢管混凝土柱基础上设置了内部钢管，由于内管受到外层混凝土的高温保护，因此其耐火性能得到改善。文章通过精细化数值模拟方法对此类双钢管混凝土复合柱的耐火性能开展研究，全面分析了内管径厚比、外管径厚比、内外管直径比等参数的影响，并且对比分析了在相同的含钢率条件下不同截面组合型式（内圆外圆、内方外圆和内圆外方）双钢管混凝土短柱的耐火极限。结果表明：在直径不变时增大内钢管的厚度以及在厚度不变时增加内钢管的直径，都有利于耐火极限的提高；在保持整体含钢率不变的条件下，不同截面组合形式的双钢管混凝土柱耐火极限相差不大，但总体上双圆钢管混凝土短柱的耐火性能偏优；另外，双钢管混凝土复合柱的...

Abstract ：
This article investigates the axial compressive performance of concrete-filled double steel tubular (CFDST) short columns composed of circular section loaded concentrically. An experimental program comprised of compression tests on short columns is carried out to examine their structural performance. Axial compression tests on conventional concrete-filled steel tubular (CFST) columns and double-skin concrete-filled steel tubular (DCFST) columns are also performed for comparison purposes. The test parameters include the diameter-to-thickness of the outer and inner steel tubes, concrete strength, and diameter ratio. The test results exhibit that CFDST short columns composed of the circular section have improved structural performance compared to its CFST and DCFST counterparts. A theoretical model is also presented to simulate the test ultimate strengths and load-axial strain relationships of CFDST columns. The existing design models proposed including the codified design specifications are evaluated against the collected test data for predicting the axial compressive strengths of circular CFDST columns. It is seen that the existing codified design models cannot yield their ultimate axial compressive strengths accurately. A practical artificial neural network (ANN) model is proposed to estimate the ultimate load of such columns loaded concentrically.

Abstract ：
In the shaking table tests of underground structures, the scale ratios of the soil and structure are inconsistent. To this end, a scaled model soil was developed in this study. Through a series of tests, the dynamic response of the model soil was investigated. A clay mixed with sawdust was designed for shaking table tests based on the predominant period similarity relationship between the structure and the foundation soil. The sawdust-mixed clay was subjected to a series of shaking table tests at Beijing University of Technology using a rigid prefabricated continuous model box (dimensions: 7.7 m × 3.2 m × 1.2 m). Through the tests, the performance of the model box and the nonlinear seismic behavior of the model soil were studied. The results are as follows: (i) The boundary effect of the model box was negligible during the test. (ii) The predominant frequencies of the model soil shifted toward lower values with increasing shaking intensity. This indicated that the model soil became increasingly softer and that the nonlinear effect of the soil was more evident. (iii) With the increase in the shaking intensity, the peak acceleration of the model soil at the same measured points increased, whereas their amplification factors decreased. In addition, the amplification factors first decreased and then increased from the bottom to the top of the soil. This might have been due to the increase in the shear strain and decrease in the shear modulus of the soil with increasing shaking intensity. (iv) The shear modulus of the soil was closely related to the confining pressure. At the same shaking intensity, the shear stress increased, and the shear strain decreased from top to bottom of the model soil. © 2020 Elsevier Ltd

Abstract ：
Shear walls of cold-formed steel (CFS) with high aspect ratios could be used in buildings with large openings such as doors and windows. However, the performance of CFS shear walls with high aspect ratios remains unclear due to limited test data. This research aimed to explore the mechanic performance and strength reduction factor of CFS shear walls with high aspect ratios through an experimental study. Five full-scale specimens were tested under monotonic loading, and the failure mechanism, bearing capacity, stiffness, ductility, and energy dissipation of the specimens were obtained. The test results indicated that shear walls with small aspect ratios typically fail as a result of connection damage to horizontal seams and corners, whilst shear walls with high aspect ratios commonly buckle at both the end stud and bottom track. As the aspect ratio increased, the initial stiffness and capacity decreased, while the energy dissipation per unit length increased due to greater flexibility. Ultimately, this study proposes a more reasonable design formula for strength reduction factors based upon a regression analysis of the test data. This will facilitate a more sustainable design approach, and fulfills current standards in engineering practice.

Abstract ：
Circular concrete-filled double steel tubular (CFDST) column is a high-performance composite column that has significant potential to be used in the construction of high-rise composite structures. This paper presents experimental and strength computational investigations on CFDST short columns that are subjected to eccentric compression load. A total of sixteen CFDST stub columns, two concrete-filled steel tubular (CFST) columns, and two double-skin concrete-filled steel tubular (DCFST) columns were tested to investigate their structural performance. The test behavior of the CFDST column loaded eccentrically is discussed and compared against its CFST and DCFST counterparts. The test results show that the CFDST column has improved strength and ductility under eccentric loading when compared with other composite columns. The strengths of the CFDST stub columns in this study together with the test strengths from the literature were used to assess the strength predictions by Eurocode 4 and AISC 360-16. It was found that the current predictions generally underestimate or overestimate the strengths. A new reduction factor for predicting the ultimate strengths of CFDST short columns under eccentric compression is proposed based on the test results. By adopting the newly proposed reduction factor and design method, the design predictions are found to be improved that provide reasonable estimations for circular CFDST columns loaded eccentrically.
