Abstract
A framework structure comprises longitudinal load-bearing elements and bracing elements interconnecting the load-bearing elements and intended to rigidify the structure and take up transverse forces. To this end the fastening of the bracing elements to the longitudinal elements is realized at least on one side of the structure by connections permitting a certain relative movement between the bracing elements and the longitudinal elements longitudinally of the structure. In such a framework structure as comprises longitudinal load-bearing elements and bracing elements interconnecting said load-bearing elements and serving to rigidify the structure and to take up transverse forces, the ends of the longitudinal load-bearing elements cooperate with jacks to compensate arising displacements.
Claims7
A method of adjusting the relative position of longitudinal load-bearing elements and transverse bracing elements connected thereto of a framework structure when the framework structure is under load, and when the load is eccentrically applied to said framework structure;
- where said framework structure comprises a plurality of spaced-aparat longitudinal load-bearing elements and transverse bracing elements interconnecting said longitudinal elements and serving to rigidify the structure and to take up transverse forces, said transverse bracing elements being connected to the longitudinal load-bearing elements on at least one side of the framework structure by connector means which permit relative longitudinal movement to occur between said transverse bracing elements and said longitudinal load-bearing elements on said at least one side of said framework structure;
- each of said transverse bracing elements comprising more than one elongate structural member and having such geometrical configuration so that said elongate structural members are secured in a geometrical configuration to retain the spaced-apart longitudinal load-bearing elements at a predetermined spaced-apart distance relative to each other;
- said method comprising the steps of:
- a. affixing said connector means between said transverse bracing elements and the longitudinal load-bearing elements to said longitudinal load-bearing elements on said at least one side of said framework structure in such a manner that relative longitudinal movement of between any said longitudinal load-bearing element and the transverse bracing elements connected thereto is allowed to occur only after a predetermined force caused by said connector means is overcome;
- and
- b. applying load to at least one longitudinal load-bearing element of said framework structure so that said load is applied eccentrically to said framework structure, the force of said applied load being of a greater magnitude than said predetermined force caused by said connector which is required to be overcome, so as to allow relative longitudinal movement between said at least one longitudinal load-bearing element to which said load is applied and the transverse bracing elements connected thereto.
