Abstract
A node and a strut connect to one another to form a spaceframe structure, in which the strut has a strut bending stiffness and defines a strut axis. The node has a main body and an arm connecting to and extending from the main body along the strut axis and toward the strut. The arm has a node end attaching to the main body, a strut end connecting to the strut and a midsection extending there between. The midsection includes a neck portion having a neck bending stiffness being less than 20% of the strut bending stiffness. The strut includes primary and secondary sections that axially slidably connect to one another to position them between adjacent respective end-fittings of adjacent nodes, and partially axially overlap and secure to one another and to the end-fittings respectively. At least one of the end-fittings connects to the strut end of the arm.
