Abstract


Mega frame structure is more and more widely with the various general volume of building construction in soft ground . Thus, the mega frame structure of the upper part of the structure to its foundation working together has been attached great importance to the academic and engineering . Therefore, the mega-frame structure of the ground deformation space research has a very important theoretical significance and practical value . It is for these reasons , the paper giant frame structure of the ground deformation space do the following: 1 . Composed with the establishment on a semi- infinite elastic foundation by the giant columns and giant elastic foundation beam space giant frame analysis model mega frame structure static and free vibration problems . Obtained by a numerical example , the actual significance of structural design and engineering conclusions . 2 . Establish a three-dimensional matrix displacement method of analysis as one of the upper structure , foundation , foundation model . Elastic foundation beam superstructure composed by giant columns and giant elastic foundation beam ; infrastructure is seen as the extension of the upper part of the structure to the underground , but the giant foundation beam unit is placed in a semi- infinite elastic foundation ; foundation of a semi - infinite elastic foundation model. Mega frame structure superstructure , foundation , foundation work together static and free vibration analysis of this model . Some valuable conclusions drawn from the analysis of example , work together for the space giant frame to its foundation , static and dynamic analysis to provide a reasonable and feasible algorithm and certain reference value conclusion .
