    structural RENOVATION Encountering Historic Metals in Renovations By Ciro Cuono, P.E., and Christopher Ribeiro, E.I.T. tructural steel has been a dominant building material for more than 100 Syears. Although steel is not considered a particularly remarkable material today, Vaclav Smil’s book, Still the Iron Age, illustrates how important iron and steel have been and continue to be in industrialized societies. For a struc- tural engineer working on historic renovations and adaptive reuse of pre-war buildings, working knowledge of the history, development, and metallurgy of structural metals is necessary for the engineer to be effective and efficient.

  • What Engineers Should Know About Bending Steel
    bending and rolling What Engineers Should Know About Bending Steel With these tips under your belt, you’ll be ahead of the curve on your next bending or rolling project. BY TODD A. ALWOOD HOW MUCH DO YOU KNOW ABOUT BENDING STRUCTURAL STEEL? Do you know what you need to show on con- struction drawings to transfer the idea of what the result should actually look like? Do you know how tight of a radius you Hcan roll a W12×19, and what to expect it to look like? If you have bending questions, who do you ask? AISC’s bender-roller com- mittee is taking steps to address these ques- tions, which are coming up more and more within the structural steel industry. Bender = Fabricator? Not so! The bender is typically a spe- cialty subcontractor of the fabricator. Benders receive the steel from the fabri- cator (or sometimes furnish it themselves), and then ship the curved steel back to the fabricator. Benders usually have limited fabrication capabilities, such as hole drill- ing and plate welding, but they are gener- ally used for smaller jobs that usually are not structural in nature. Typical fabrication is still carried out through the main project fabricator who organizes the steel package from procurement through delivery to the site for erection. Kottler Metal Products, Inc. Kottler Metal Products, Todd Alwood is the senior advisor for AISC’s Steel Solutions Center and is Secretary of AISC’s Bender-Roller Committee. MODERN STEEL CONSTRUCTION MAY 2006 Common Terminology and Essential Dimensions for Curving Common Hot-Rolled Shapes There’s only one type of bending, right? Nope! There are five typical methods of bending in the industry: roll- ing, incremental bending, hot bending, rotary-draw bending, and induc- tion bending.

I make an attempt to point out some specific safety precautions as they come up, but there is no way I can point out every conceivable danger. I'm not a professional foundryman, scientist, or engineer, just a hobbyist—so there may be dangers that I don't even know about. For that matter, any advice I give could be wrong or even dangerous in certain situations. I can't be held responsible for any harm that comes to person or property as a result of following my advice or using any of the information in this book. Remember, the extremely high temperatures that liquid metal can reach are more than enough to send you to the hospital or kill you, or to set fire to anything nearby (like your house).

  • Comparison of Different Material Cutting Technologies in Terms of Their Impact on the Cutting Quality of Structural Steel
    M. Harničárová, J. Zajac, A. Stoić Usporedba utjecaja različitih tehnologija rezanja materijala na kvalitetu reza konstrukcijskih čelika ISSN 1330-3651 UDC/UDK 621.791.94:669.14.018.29 COMPARISON OF DIFFERENT MATERIAL CUTTING TECHNOLOGIES IN TERMS OF THEIR IMPACT ON THE CUTTING QUALITY OF STRUCTURAL STEEL Marta Harničárová, Jozef Zajac, Antun Stoić Subject review The paper deals with a comparison of the most frequently used thermal cutting technologies applied to the structural, low carbon steel EN S355J0 in engineering enterprises with a focus on experimental measurement and evaluation of characteristics of the heat affected zone. It gives a mutual comparison of these technologies in terms of the achieved heat affected zone. The goal of this paper was to use the property changes in the used material (affected by laser, plasma arc and oxygen cutting) as the quality indicator of the cutting process. Keywords: heat affected zone, metallography, structural steel, quality, thermal cutting Usporedba utjecaja različitih tehnologija rezanja materijala na kvalitetu reza konstrukcijskih čelika Pregledni članak U radu se daje usporedbanajčešće korištenih toplinskih postupaka rezanja, koje koriste proizvodne tvrtke, u primijeni na konstrukcijskom , nisko ugljičn om čeliku EN S355J0 s naglaskom na eksperimentalna mjerenja i vrednovanje svojstava zone utjecaja topline. Rad prikazuje usporedbu tih tehnologija u kontekstu dobivene zone utjecaja topline. Cilj ovog rada je korištenje spoznaje o promjenama svojstava korištenog materijala na površini reza (dobivene laserom, plazmom i plinskim rezanjem) kao pokazatelja kvalitete procesa rezanja. Ključne riječi: konstrukcijski čelik, kvaliteta, metalografija, toplinsko rezanje, zona utjecaja topline 1 technologies [10] for a given type of steel in practice. The Introduction measurements of micro hardness within the heat affected Uvod zone provide an important piece of information and vision about the thermal influence on a basic material.
