Knowing the design codes\u00a0and design criteria that we will use at the start of our task is a must in Structural Design. This is the basis and guidelines for designing a proposed project. Design code to use in our design depends on the location of the project. Generally, the structural design criteria adopted for the project is based upon the principle of the codes and standards. References, supplementary codes, and local codes are also considered when required.\n

\nThe most common design codes adopted by most countries are according to international codes and standards like the British Standards, Euro Codes, and\u00a0American Codes. Each code has its sections intended according to its uses. For example, when using American codes we can refer to ASCE 7 for design loadings consideration, UBC-97 for seismic loadings, ACI 318 for building code requirements for structural concrete design and AISC for steel structures.

\n\nSometimes, the uses of equivalent codes are also accepted by the authority in jurisdiction. So as a designer, it is important to know the codes and standard that is acceptable from where the project is located.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

After identifying the codes that we are going to use in the design, the next thing to consider is the load considerations and calculations. The load considerations are depending on the type of occupancy of the project. Here the three basic loadings of a building are being assigned. The dead load (DL) that usually composed of the self-weight of the member or a structure, the super-imposed dead load (SDL) that comprises of the floor finishes and the weight of the partitions, and the live loads (LL) that constitutes the movable loads that the structure may carry. Depending on how tall the project is, a wind load and seismic load shall also be considered accordingly. These load consideration is being specified on the design code and standards. In the case of the American code, ASCE 7 can be referred to.

\nThe load combinations that we are going to use are also being considered. The standard load combinations according to Ultimate Limit State (ULS) and Working or Service Limit State (SLS) are used. The ULS and SLS are being specified and available also in the design code that we are previously considered.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The framing system is a vital part of the structural design. It is where the overall safety of the structure will rely upon. In this aspect, the structural engineer should come up for a better solution on how the project will be supported structurally. At this stage, the designer should study and review the possible framework of the project without compromising the safety and soundly of the building that we are designing. The standard thicknesses of slabs, dimensions of beams and columns, its location and orientations are being considered initially. Proper coordination in other departments like the architectural and MEP should also be observed. Prior to structural modeling, a draft framing system is highlighted at first in the architectural drawing to make sure that no architectural aspects are being compromised. The proposed framing is then be verified via manual calculations and through the use of structural software.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Once the proposed framing has been finalized, we will verify the adequacy of it through structural modeling. Using available structural software in the market, structural modeling can be easily done. Using 3-dimensional modeling structural software like ETABS and Staad.Pro, it is convenient for the designer to extract the design forces needed in the design of structural members such as the design of beams, slab, columns and the design of footings. The designer can also perform other necessary checks accordingly.

For some reason that the structural software is not available, the designer can do a manual design. But designing the structures manually is limited for small projects, not to mention the amount of time it will create during that process. Considering the design phase nowadays, it is still recommended to model the proposed project using structural software and that manual calculations can be used for some individual checks on structural members. A spreadsheet of member design can also be used.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Perhaps the good thing about structural modeling is that the design forces that you need in the design are readily available whenever you need it. In this reason, the designer should check or design the reinforcement in the beams according to the loads that we inputted.Design of slab\u00a0and punching reinforcement check is required. Vertical members design such as\u00a0shear wall design\u00a0and\u00a0design of columns\u00a0and check for buckling are necessary. More importantly, the extracted forces or the column loads that the footing will carry according to SLS load combinations for\u00a0foundation\u00a0should be design.\n

\nBut of course, all of the basic requirements for structural member design can always be verified by manual calculations. So it is always your prerogative.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

After all the design procedure above has been completed, a draft sketch of structural framings or structural markups, its design and structural schedule shall be handed over to structural draftsman for him\/her to interpret it into a structural drawing. In this stage, structural design engineer supervision is required to make sure that every detail in structural drawings is accounted for. A final review of the produced structural drawing should also be considered upon submission for building permit approval.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
