Abstract: A tower monitoring system for monitoring a remote tower for structural evaluation and analysis. The tower monitoring system includes a sensor unit that takes tower data readings that include displacement readings. The sensor unit provides the tower data readings to a ground control unit near the tower. A remote server is in communication with the ground control unit and includes a secondary source of data, such as historical data of the tower, current data or historic data from nearby towers, and nearby weather and geological data. The monitoring system implements a modal analysis to determine contributions to the displacement readings and alarms an operator if the modal readings indicate structural stress beyond a predetermined threshold. Data is saved and can be used in a trend analysis to review any changes in the tower displacement readings over a period of time.

Abstract: Disclosed herein are systems, methods, and circuits configured to monitor the displacement of a tower, report the monitored displacement via a networked connection, and determine that the tower is in a non-optimal state. By providing the aspects disclosed herein, an operator of a tower may optimize the tower's function, and potentially prevent the tower from breaking at an earlier stage.

Abstract: A tubular member, which is made of steel and which is useful as an upright, structural member in a pole, pylon, or tower, is filled at least partially with a foamed material protecting said member against internal corrosion and against pest infiltration. The tubular member comprises plural sections, which have end flanges and which are bolted together at the flanges, and comprises gaskets to prevent the foamed material from being extruded between the flanges.

Abstract: In a steel tube filled at least partially with a cementitious material, which is pumped into the steel tube and which is allowed to cure, and comprising plural sections, which have end flanges and which are bolted together at the flanges, the flanges contacted by the cementitious material have gaskets to prevent the cementitious material from being extruded between the flanges contacted by the cementitious material before the cementitious material has cured. The flanges having the gaskets are external flanges. The tube sections meeting at the flanges having the gaskets have notches, within which the gaskets are seated, so as to allow the flanges to have flange-to-flange contact, except where the gaskets are seated in the notches.

Abstract: A barrier, which is intended to intercept a crashing airplane before it reaches a target, comprises an array of spaced towers. Each tower is several hundred feet tall. Each tower comprises a trusswork including three steel tubes, which are filled with a cementitious material, such as grout, in a triangular array wherein one tube is closer to the target. Guys interconnect the towers to one another and to ground anchors. Each tube comprises plural sections having end flanges, at which those sections are bolted to one another, and gaskets to prevent the cementitious material, as it is being pumped, from being extruded between the flanges before it has cured.
