Description

A system and method for estimating the amount of remodeling slab dismantling materials using moment calculation, and a recording medium recording a computer-readable program for executing the method The present invention relates to construction-related technology, and more specifically, to a system and method for calculating the volume of demolition related to the remodeling of apartments, etc. Unlike general new construction or reconstruction, remodeling involves structural changes or the expansion of internal residential spaces, such as an increase in the number of floors, reinforced structural standards, and changes in load paths due to the removal or installation of existing members. Therefore, a floor plan design that takes into account the amount of structural elements, such as walls and slabs, to be removed is required. Plan design candidates prepared in the early stages of the project are limited to expressing design concepts such as section division and floor layout; consequently, the project proceeds with plans that do not account for the amount of structural framework to be demolished. Meanwhile, looking at recent issues in remodeling projects, there is a trend toward proceeding with aggressive expansion designs that involve extensive structural changes and the demolition of numerous walls. Due to these structural risks, projects are failing to pass structural reviews, resulting in many cases where project plans are being re-established. In this process, a vicious cycle is repeating itself in which project costs increase due to project delays caused by the redrawing of design plans and frequent design changes.

FIG. 1 is a schematic block diagram of a system for calculating the volume of remodeling slab demolition using moment calculation according to one embodiment of the present invention, and FIG. 2 is a schematic flowchart of a method for calculating the volume of remodeling slab demolition using moment calculation according to one embodiment of the present invention. A system for calculating the volume of remodeling slab demolition using moment calculation includes a drawing information input unit (110), a drawing generation unit (120), a combined drawing generation unit (130), a load matrix generation unit (140), a bending moment calculation unit (150), a modified area extraction unit (160), a demolition range calculation unit (170), a demolition volume calculation unit (180), a user output unit (190), and a preprocessing unit (200). The bending moment calculation unit (150) further includes a continuous beam generation unit (152) and a beam moment calculation unit (154). The drawing information input unit (110) receives coordinate information of members and loads for the design drawings before and after remodeling, respectively. To this end, the preprocessing unit (200) can extract coordinate information of members and loads for the input design drawings. With this configuration, the preprocessing process is performed using a CSV coordinate method rather than an image method, thereby minimizing the occurrence of errors. The drawing generation unit (120) generates a member drawing with member information displayed and a load drawing with load information displayed for before and after remodeling based on the input coordinates of the member and load. Through preprocessing, the coordinate information of the member and load before and after remodeling is
