<p>A modular spaced framed structure is constructed using uniform components to provide the desired geometry of the modular structure. The structure is comprised of a plurality of rigid Y-shaped devices, each of which has three tubular branches which are disposed at respective predetermined space angles with respect to one another, and a plurality of panels spanning the spaces between the devices. Linear coupling members are also provided for interconnecting abutting branches of adjacent devices. In the preferred embodiment the three branches of each device are oriented at respective space angles of 108 DEG , 108 DEG and 108 DEG so that a tower structure having a pentagonal horizontal cross-section is formed. Each successive level of the tower below the apex has a substantially greater area than the level above it so that the legs of the tower are inclined to provide greater resistance to earthquake forces. This type of structure is particularly well-suited for supporting offshore platforms and can be efficiently assembled on site due to the modular nature of the construction. The structure can be reinforced by inserting cables into the tubular branches to prestress the connections and pouring a filler material such as concrete into the branches to enhance the rigidity of the tower structure.</p> |
