High-frequency mechanical impact (HFMI) is an efficient post-weld treatment technique that enhances fatigue strength in metallic welded structures. Steel or steel-concrete composite road bridges, where the limit state often governs design, compose one category of structures can benefit from application this technology. To assert improvement using HFMI, induced compressive residual stresses must...
b fast and highly reliable method of inspecting minule solder joints of high-density rnouaed devices hns been dcveloperl. It uses two techniques to detect all types of defects, such as unsoldered leads. solder bridges. and mis-aligned leads. One applieszxternal Form to solder joints with an air jet. which vibrates w shifts unsoldered leads. The vibration and shift is detected as a change in the...
In this paper, two sets of comparative fatigue tests on weathering steel-concrete composite girders were carried out in the context girder bridges. The load-deflection relationship under loading different environments was investigated contrastively. experimental results show that coupled effect corrosive environment and load, steel still shows obvious corrosion; simple load has no significant s...
Soil–steel composite bridges (SSCB) have become increasingly popular for short-span as an alternative to concrete slab mainly due their low initial cost, rapid manufacture, simplified construction, and geometrical adaptability. SSCBs a variety of applications can be used over waterways or roadways. While conventional tend lose load-carrying capacity degradation, gain strength because backfill s...
