Abstract: A high-power seismic wave early warning method is provided to use an earliest-arriving seismic wave to estimate a maximum power value of a later-arriving high-power seismic wave for a target site. When the estimated maximum power value of the later-arriving high-power seismic wave is greater than a warning value, an earthquake early warning is transmitted to an earthquake early warning device that is located at the target site.

Abstract: An energy dissipation device includes a primary core module, a housing module, first and second outer plates, an energy dissipation unit, first and second preload tension members and a resilient compression unit when the primary core module and the housing module are subjected to an external force, the first and second preload tension members stretched by the external force, and the resilient compression unit is compressed, such that relative movement between the primary core module and the housing module is generated. The energy dissipation unit generates a retarding force during the relative movement between the primary core module and the housing module, so as to dissipate the kinetic energy generated as a result of the external force.

Abstract: An automated multi-pass welding method is provided. An optical measuring instrument measures a welding space to obtain reference geometry information, and then the reference geometry information is inputted into an AI model to obtain control parameters that are used by a welding device and a robotic arm as operation settings to perform welding. The optical measuring instrument measures the welding space after the welding to obtain post-welding geometry information for a computerized control device to generate a classification result. When the computerized control device determines to form a next weld pass based on the classification result, the aforesaid actions are repeated until the computerized control device determines to stop welding.

Abstract: A method for identifying prestress force in single-span or multi-span PCI girder-bridges is provided. The method includes non-destructive steps for obtaining a set of parameters of the PCI girder-bridge under investigation, and combines various analyses to identify the change of prestress force. Therefore, the losses of prestress force are tracked and predicted. The method does not cause structural damages along the PCI girder-bridge, and the cost of the identification is significantly decreased.
