Reinforced Concrete Frame Structure

Reinforced concrete frame structures are widely used in a variety of livelihood projects, such as housing, teaching buildings, hospitals, etc. Therefore, in order to guarantee the quality of concrete frame structures, one has to do a lot of pre-preparation work. So, such as the design phase is important. The designers concerned usually need to plan floorplans, elevations, sections, and various structural construction drawings. Then, for the building elements(components), the choice of materials is crucial, as this affects not only the quality of the construction but also the subsequent quality of the construction as well as the construction costs and even the environmental impact(e.g. the production of concrete).

 

  • ONTOLOGY OF REINFORCED CONCRETE FRAME STRUCTURE
  1. Purpose: This ontology is built for representing concepts needed for the conceptual design of the concrete structure, mainly targeted at architectural design and structural design.
  2. Domain: Building components, main material, and uses.
  3. Intended Use: The ontology is intended to be used as knowledge representation to support the creation of parametric models with software such as SAP, PKPM, CAD, and related plugins, which mainly focus on structural analysis and design.
  4. Intended Users: Designers and structural engineers.

DEVELOPMENT OF AN ONTOLOGY

To develop an ontology for reinforced concrete frame structural systems to help designers, engineers, and newcomers to the industry gain a basic understanding of the structural components and concepts, as well as some of the architectural elements that need to be taken into account during the design phase in order to optimize future design solutions.

  • PARAMETRIC MODEL FOR REINFORCED CONCRETE FRAME STRUCTURE

It focuses on creating a parametric model in the Reinforced-concrete frame structure. Before listing the parameters, we should first have a basic understanding of the structure to be created, i.e, what is a frame structure? Or what are the main components of a frame structure-of Beams, slabs, columns, and foundations.

Of course, there are many controllable indicators to control the structural performance of a frame structure during its design.

High-performance criteria:

  1. Lateral stiffness of frame beam: This index is controlled by the height-to-width ratio(h/b) of the beam. Beams with excessive cross-sectional height-to-width ratio have higher linear stiffness and may appear as strong beams and weak columns. In addition, a beam with a too large an aspect ratio has a larger force on the concrete at the bottom, which may produce brittle damage. In short, it is unreasonable. By limiting the aspect ratio, the lateral stiffness of the beam is limited to ensure the stability of the structure. In Dynamo, a small and easy operation is created to determine whether the beam section size set is reasonable.
  2. Reinforcement: A single-span beam section is selected for reinforcement calculation and checked for reasonableness. Also, the beam section is considered a single reinforcement rectangular section.
