摘要

焊接空心球面接头广泛应用于大跨度空间结构、桥梁和工业设施中。本研究提出了一种基于焊接沉积的焊接复合材料加固方法。采用手工电弧焊（MAW）工艺，在焊接沉积的基础上进行坡口加固。通过试验试验和有限元分析，研究了这种加筋钢结构的抗压能力。研究了不同补强位置、焊接残余应力范围、几何参数和焊敷厚度对焊接复合材料抗压能力的影响。结果表明，所提出的基于焊接沉积的焊接混凝土混凝土加固方法可有效提高其抗压能力，为焊接混凝土混凝土的长期加固提供了一种有效的新方案。

Enhancement of the load-bearing capacity of WHSJs based on welding deposition

The welded hollow spherical joints (WHSJs) are widely used in long-span spatial structures, bridges and industrial facilities. This study proposes a reinforcement method for the WHSJs based on welding deposition. Manual arc welding (MAW) process is used to reinforce the WHSJs with grooves based on welding deposition. The compression capacity of such reinforced WHSJs is investigated through experimental tests and finite element (FE) analyses. The effects of different reinforcement positions, the range of welding residual stresses, the geometric parameters and the welding deposition thickness on the compression capacity of the WHSJs are studied. The results show that the proposed reinforcement method of the WHSJs based on welding deposition can effectively improve the compression capacity, providing an effective new solution for the long-term reinforcement of WHSJs.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
