Research On Program And Problems Of Shallow Foundation Design Of Electronic Edition Of Code For Design Of Building Foundtion In Nanjing Area

It is introduced that about program of shallow foundation design in electronic edition of code for design of building foundtion in Nanjing area. The following works are made:The first is that the program design is completed. It has there parts: constructing program framework,pre-processing and post-processing,the core of calculation. Some preparing work such as program configuration,system prescribe,relationship of geometry,data structure are thinking over in constructing program framework, which are ready for constructing other parts. Every program of each foundation type has the first initialization,parameters setting,the second initialization,tentative calculation,checking,caculation,mergering results and creating calculation statements. Pre-processing and post-processing are important part for communicating between program and design staff. The pre-processing is the prograss including reading data,parameters setting and initializing data for preparing data for caculatiing steps. The post-processing is the prograss including mergering results,drawing and creating calculation. The core of calculation is the key of program, includes checking bearing capacity of subsoil,checking soft underlying stratum,checking bearing capacity of subsoil of earthquake,caculating internal forces and distributing steel,checking partly press and caculating settlement. Each type has its own checking and caculating different from other types.The other is that solving problems in some methods that are not described clearly in some interrelated literature. Problems of single footing are classifying about results,determination of dimension of combinational column on combinational foundation,determination of bending moment on superface of combinational foundation and determination of partly press area when there is angel between column and foundation; the problems of strip foundation are determination of torsional moment on some section in checking torsion resist. The program still has some bugs and it need consummating to be a better edition in the future.
