Design code for structural steel materials

But it seems like A36 is the most commonly used in the industry, so it may be the most optimal and economical choice.In summary, bidders are proposing the use of ASTM A36 material instead of S275 J2 or S355ML/NL for structural steel in order to adhere to international standards and achieve the most optimal and economical design. While A36 may be the lowest quality in terms of yield strength, it is also the most commonly used and potentially the most cost-effective option. The final decision should depend on the specific application and needs of the project.

Bidders propeses ASTM A36 material istead of S275 J2 or S355ML/NL for structural steel (Piperack, Equipment Structure, etc.) on the basis of international standards for most optimal and economical design. Is it really optimal? pls explain why

Bidders propose what they can make money on. What do the data sheets say?

ACI, AISC, ASCE and ASTM will apply to Civil and Structral. So pls help which of one is optimal and economical ASTM A36 or S275 J2 or S355ML/NL? Thank u

Well, I've heard of ASTM A36 and know where to go to find the details, if need be. :wink:

S275 J2 or S355 ML/NL I've never heard of and wouldn't know where to go for the details without doing some digging. :frown:

From what I know, A36 is the lowest quality among those if we compare the yield strengths, which is the most important metric in most cases. It is probably the cheapest, though I don't know the steel prices. You can refer to this:

Which is best? That depends on the application.
 

1. What is the purpose of a design code for structural steel materials?

A design code for structural steel materials provides guidelines and standards for designing safe and efficient structures using steel as the primary construction material. It ensures that the structures are able to withstand the intended loads and forces, and that they meet safety and performance requirements.

2. Who creates and updates design codes for structural steel materials?

Design codes for structural steel materials are typically created and updated by organizations such as the American Institute of Steel Construction (AISC) or the International Organization for Standardization (ISO). These organizations have committees and experts who review and revise the codes based on new research, technology, and industry practices.

3. What are the key factors to consider when designing with structural steel materials?

When designing with structural steel materials, key factors to consider include the intended use and function of the structure, the expected loads and forces it will experience, the location and environmental conditions, and the available resources and budget. It is also important to comply with local building codes and regulations.

4. Are there different design codes for different types of steel structures?

Yes, there are different design codes for different types of steel structures, such as buildings, bridges, and industrial facilities. These codes take into account the unique requirements and considerations for each type of structure and provide specific guidelines for their design and construction.

5. How do design codes for structural steel materials impact the construction process?

Design codes for structural steel materials play a crucial role in the construction process by providing a framework for engineers and architects to design safe and efficient structures. These codes also ensure consistency and standardization in the materials, fabrication, and construction methods used, which can help streamline the construction process and reduce costs.
