A method of constructing a reinforced concrete floor structure or wall structure, including: fabricating a precast panel substantially from concrete including a first set of parallel conduits extending through the panel, wherein the conduits open to opposite sides of the panel; moving the panel into its final position on a building site; and inserting tensioning cables through the conduits and tensioning the precast panel in the direction of the conduits to form a reinforced floor structure or wall structure, and a dowel connecting system for joining adjacent precast building panels, the system comprising elongated hollow dowel members cast in at the edges of two or more precast building panels such that when the building panels are positioned adjacent to each other their respective dowel members are co-linearly aligned; and a dowel piece to be inserted into a recess of the co-linearly aligned dowel members and to extend across the building panels, wherein the recess of the dowel members is adapted to be filled with grout to anchor the dowel piece therein and thereby structurally joining adjacent building panels.

A connector is disclosed for use in forming a joint between a first surface and a second surface. The connector comprises a housing. The connector also comprises a tendon. A portion of the tendon can protrude from the housing through a seal. The seal is configured to sealably cover an open end of the housing such that the tendon can move through the seal and laterally sideways across the open end together with at least a portion of the seal. Also disclosed is a connector system for use in forming a joint, and a method of installing a connector to form a joint, between a first surface and a second surface. The connector system and method comprises and makes use of the housing and the tendon.

Structural member for a reinforced stud wall including a tie rod. A horizontal longitudinal hollow bearing member having a horizontal longitudinal axis and horizontal and parallel top and bottom walls extending along the horizontal longitudinal axis. The top and bottom walls are configured to support a downward compression force transverse to the top wall from the tie rod when the tie rod is attached to the top wall. First and second web flanges connect the top and bottom walls to form first and second I-shaped cross-sections joined together side-by-side, the web flanges extending along the longitudinal axis of the hollow bearing member. The web flanges are configured to transfer downward compression force on the top wall to the bottom wall. Opening through the top and bottom walls allows the tie rod to extend vertically therethrough, the opening being confined within a space between vertical portions of the web flanges.

Method of design and manufacturing concrete structures subjected to relevant cyclic loads along their service lives, as wind towers, and a fatigue testing machine. The method consists on the design of concrete structures conditioned by cyclic loads considering a fatigue strength value specified by the project as one of the main design parameters, which will be verified during the manufacturing phase as one of the control parameters of the quality assurance plan by performing fatigue strength test on concrete samples representative of the concrete structural elements produced on said manufacturing phase. The method allows to decouple the concrete fatigue strength from the compressive strength of the material, which is why includes a verification of the fatigue strength as a part of a quality assurance plan of production according to a new developed procedure.

A method of manufacturing a pre-stressed beam or panel and the resulting beam or panel are described. The method includes providing a timber-based component (1); providing a pre-stressing member (9) arranged along the timber-based component; applying a tensile force to the pre-stressing member (9); providing concrete anchors (11a, 11b) at locations that are spaced apart along the timber-based component (1); coupling the pre-stressing member (9) to the concrete anchors (11a, 11b); and releasing the tensile force on the pre-stressing member (9) to transfer a compressive force to the timber-based component (1) through the concrete anchors (11a, 11b) to form a pre-stressed beam or panel.
