| Formwork engineering has a significant impact on the quality of concrete pouring,construction period and cost,and is an important part of engineering construction organization design.Due to its excellent performance,aluminum alloy formwork has been widely used in my country,but the efficiency of formwork design to construction is still not high,which affects the construction efficiency of formwork engineering.With the emergence of Building Information Modeling(BIM)technology and the rise of heuristic intelligent algorithms,traditional aluminum alloy formwork design and construction problems have new solutions.This research combines BIM technology with heuristic intelligent algorithm,proposes an intelligent mold matching method for aluminum alloy formwork,establishes a mathematical model and solving algorithm for mold matching optimization,analyzes the information interaction requirements between BIM and numerical analysis platform,and proposes a force analysis method for aluminum alloy formwork.A collaborative design method is formed,which is of great significance to the theoretical improvement and engineering practice of the design of aluminum alloy formwork.The specific research contents are as follows:(1)An automatic and intelligent two-stage mold matching method for aluminum alloy formwork is proposed,and the non-rectangular right-angle boundary mold matching problem in the mold matching area is considered.Through on-the-spot investigation,analysis of engineering drawings,reference to literature and standard standards,etc.,the principle of deepening design of aluminum alloy formwork mold matching is studied,and the general principle of intelligent mold matching design based on the "aluminum beam-template-aluminum beam" mold matching method is determined.This method Considering the non-rectangular right-angle boundary problem of the mold matching area,the automatic mold matching design is completed.(2)The optimization mathematical model corresponding to the two-stage mold matching was established,and the sub-objective mathematical model was established for larger-scale problems.The goal of the minimum number and variety of aluminum alloy templates was to use the differential particle swarm algorithm to solve the problem,and the algorithm flow and matching were studied.Mold optimization process.Based on the C# language programming for the secondary development of Revit,the solution results are compared with the actual mold matching of the two engineering cases.After the aluminum alloy template specifications are increased,the number of templates is reduced by 19.2%,29.1%,and the type of templates by37.5%.%,28.6%,the mold matching optimization effect is good,which proves the feasibility and effectiveness of the algorithm.(3)Finally,on the basis of the BIM model,combined with the finite element software ABAQUS for collaborative automatic verification,and the information exchange between the model and ABAQUS,the preliminary process framework for the design and construction collaborative analysis of aluminum alloy formwork based on the BIM system is proposed.The standard component is used as an example to illustrate the process of collaborative design of solid elements,and the process of automatic verification of formwork solid elements and regional shell elements is determined.The analysis results of the two verification processes provide reference and verification methods for engineering mold matching design.The process can realize automatic verification. |
