Structural engineering or structural design is a process that you go through to complete a construction project. There are three main phases, which include the planning phase, design, and construction phase.
During the planning phase, the factors that go into a structure such as concrete buildings or steel buildings are taken under consideration. You have to look at things such as the building layout as well as the dimensions of the structure you’re going to be working on. The functions that you want for the building is going to be a part of the decision-making process. You also have to consider sociology, ascetics, the environment, and how the building may impact the economy.
In structural engineering, the next phase is the design phase. This is where you look at the design of the actual structure. You will look at the proportions, dimensions, the connections, structural members, and other materials you may be working with.
The next phase is the construction phase. This is where you get your equipment and materials and begin the process of putting up the structure. you may have to hire labor, and you could run into difficulties where you have to redesign certain parts of the structure.
In structural design, there are some guidelines that you have to follow. A lot is going to depend upon the actual structure you want to design. General structural design guidelines are explained briefly in the below section:
The designer has to look at the conditions of the building site. Some things to consider include:
There will be different loads on your structure. You need to consider these before you build. This has to factor in the building process. here are some of the loads that you need to consider.
The dead load is formed by the self-weight of the actual structural members. These include the beams, columns, finishing, slab loads wall loads, plastering, and so on. Any element that will be stationary and placed permanently on your structure should also be included as part of the Dead load. The self-weight of a dead load of any structural member is calculated as a product of its self-weight and the volume.
The load that a structure is subject to when it is occupied. these can be dynamic or static in nature. The load may or not be present during the use of the structure. For example, in industrial structures and buildings, there can be a live load from maintenance tools, people, and so on.
Different structures will have a different live load. For example, for a residential building, the live load is 40 psf, and the value for a live load on lobbies and corridors of offices 100 psf. ( I changed to USA units)
The region where the structure is to be built will have a recommended minimum load value. In the USA, you can get a live minimum load rating for a building through ASCE 7.
When you look at the live load in the design of a structure, you also have to consider that the structure may be expanded in the future. The load probabilities during the lifetime of a structure must be considered when you design for a live load as things may change.
On the windward side of a site, the wind load will act horizontally on the building’s surface area. Any site that is under construction or being considered has a wind Zone. The maximum wind speed area is calculated based upon the wind zone. You can get a wind map of the area where you want to build that has this sort of data.
The building orientation and the surface area of the structure impact the wind speed and convert this into force. The wind direction impacts the wind Force calculation. When you calculate for a wind load, you don’t have to take into consideration the shape of the building or the structural member. A wind load is calculated for a structure that is subjected to wind force or for structures that are built to resist wind.
Guidelines for the calculation of wind force on a structure can be found in ASCE 7-95. You can also look at applicable codes based upon the location of the structure or building.
ASCE 7Or other applicable codes will determine the design for a seismic load. You can use this for the calculation of earthquake forces.
When you construct a building or other structure, you have to look at the relevant codes. you can look at ACI 318-14 or whatever other code is applicable to your project.
Steel building fabrication must conform to AISC-ASD The message for structural design is based upon the practices of the local area. the three methods used include:
When designing a structure, you have to look at the following standard codes, which are as follows:
Structural Design Guidelines, these are just a few of the points you need to consider with structural design. It doesn’t matter whether you’re working with steel buildings, concrete buildings, or other structures. There are certain rules and regulations that you have to follow. You must ensure that the structure is completed in the right way. This can only be accomplished by an understanding of the entire project.
