light steel structure CAD software functions and applications of the STS

Construction steel has the advantage of also becoming more prominent. The improvement of the quality of steel, the type of the rich, the perfection of the design theory for the development of the steel structure to lay the foundation, steel, up especially light light steel structure in China's rapid development. CAD technology development and to promote the success to complete the steel structure of the computer analysis by means of computer-aided design software to optimize the design and drawing work, on the one hand, can provide accurate calculations and drawing tools to the engineering design and improve design efficiency, safer design economic,
The other hand, will also play a significant role in promoting the further development of the steel structure. PKPM Series software is the most widely set of integrated CAD software, won the National Science and Technology Progress Award, is the only independent platform for the computer-aided design system, has now become a including architectural design, structural design, equipment design, integrated CAD system, including the multi-storey and high-rise, industrial plants and civil construction, superstructure and all kinds of basic structural design, and are to the development of integrated and intelligent direction. In this case, the China Academy of Building Research PKPMCAD engineering department from May 1995 to organize forces to study the STS steel structure CAD software to develop their own copyright, independent development of the software development to PKPMCAD Engineering Department of CFG Chinese graphics support system as a platform, to PKPM Series software PMCAD PK based. The functional requirements of the STS: the integration of CAD software, features include input from the steel building model, the cross-section optimization, structural analysis, component strength and stability checking, node design, draw until the construction details; software is applicable to multi- , high-level framework, plane frame, continuous beam, light steel portal frame, bent frame, frame - bent,
Steel truss and other structural forms; software requires simple operation, high degree of automation, user-friendly, easy to learn and use; construction drawings detailing standard drawings shall prevail, and provides convenient editing tools; software module PKPM series can interface with other modules; first STS become mainstream domestic steel CAD software, and then expand the foreign version of the specification, the international software market. 2STS software technical conditions as a professional steel structure engineering design software, must comply with the existing national norms, rules and standards. The STS software development based primarily on: the cold-formed steel design specification of the design of steel structures (GBJ17-88) (GBJ18-87) "Tall Buildings steel structure technical regulations" (JGJ99-98) "door frame light house steel structure technical regulations (CECS102: 98) light steel structure design point of order "(DBJ08-68-97) In addition, STS software follow the commonly used steel structures design manual, the provisions of the standard map. The About 3STS software function 31 model input STS model inputs can be used three-dimensional and two-dimensional methods.
The use of interactive three-dimensional modeling, guiding the user layer by layer the layout layers plane and floors, and then enter storey establish a description of the overall structure of the building data, three-dimensional modeling program has strong load statistics and conduction calculation function, in addition to the calculated weight, also done automatically calculated from the floor to the light steel structure beam, secondary beam to the main beam, main beam to the load-bearing columns, walls, and then spread from the upper structure based plus part of the applied load, can be easily established throughout the building load data. Section type of three-dimensional modeling of China and the world standard section steel composite section, welded H-beam (including a wedge-shaped cross-section), custom cross-section of the tube, box-shaped, Z-shaped, grooved steel pipe, concrete, steel reinforced cross-section in the form of concrete section, applicable to the needs of the various structural forms. Two-dimensional modeling data that can be generated by the three-dimensional modeling of the data plane frame, continuous beam data file automatically generated can also employing machine interaction to generate convenient to establish the model of the plane frame structure. Two-dimensional human-computer interaction modeling framework, portal frame, bent frame bent, continuous beams, trusses, brackets, continuous beam, a variety of structural forms of model can create various types of plane frame gantry frame, frames, trusses, curved axis also provides fast input wizard to quickly enter, you can enter a variety of roles in the form dead load, live load, wind load (can automatic layout), crane load (including pumping pillar crane load) parameters calculated and seismic.
Section type in addition to the type of cross-section of the three-dimensional modeling, two-dimensional modeling to provide the type of cold-formed steel composite section, solid web composite section, lattice composite section, composite beams, arbitrary cross-section. 32 the section optimization-section optimization is to meet the specification requirements, looking for the smallest amount of steel section size. STS software can light steel portal frame and steel truss section optimization. Gabled frames are often used in the variable cross-section member, so the constraint variables are optimized big endian, the height of the small end, the upper and lower flange width, thickness, web thickness, seven factors, STS software can be in the range of variation of the automatic or manual definition inner and quickly find the smallest cross-sectional dimension of the amount of steel. The truss optimization can be carried out lever member packet, divided into a group of the lever member has the same cross section after optimization. The optimization procedure is faster and better applicability. The 33 structure analysis and member checking STS three-dimensional, two-dimensional modeling data can interface three-dimensional analysis procedures and plane frame analysis program for structural analysis and member checking.
