Deformacinių siūlių sujungimo sistema HSD naudojama skersinių jėgų perdavimui pastatų/statinių siūlėse, tokiu būdu sumažėja nevienodi pastato nusėdimai ir poslinkiai dėl skirtingų deformacijų poveikio. Priklausomai nuo HSD elemento, sujungimo sistema leidžia horizontalius pastato poslinkius išilgine kryptimi arba išilgine ir skersine kryptimis, kurie atsiranda dėka susitraukimo, valkšnumo arba temperatūrinių pokyčių. Inkarinis sujungimas HSD leidžia jėgos „slydimą" inkaro ašies kryptimi. Paprastai inkariniai sujungimai leidžia skersinių jėgų perdavimą laisva kryptimi. Dideli našumą gali garantuoti tik inkarai, kurie paskirsto apkrovą. Tais atvejais jeigu reikia įvertinti šonines apkrovas, būtina naudoti elementą HSD-V, kuris leidžia skersinių jėgų perdavimą išilginę ir skersinę kryptimis. Tuo atveju aktyvi jėga perduodama tik viena kryptimi.
