Abstract

The article describes the analysis of the behaviour of structures from prefabricated reinforced concrete in earthquakes, where the most important structural elements ensuring, seismic stability of buildings, are embedded parts and their welded joints. Development and introduction of effective types of welding in structures operating under the action of seismic loads, can improve the reliability and quality of construction. It is established that in the manufacture of embedded parts of reinforced concrete structures for mass construction it is recommended contact relief-spot welding for the lapping connection of anchor rods with platinum [1]. Compared with manual arc welding, this method provides high productivity, stability of strength and efficiency of welded joints.
