Advantages and Disadvantages of Steel StructuresAccording to Francis D. K. Ching (Author of Building Construction Illustrated), conventional steel structures are constructed out of hot-rolled beams and columns, open-web joists, and metal decking. Since structural steel is difficult to make on site, it is generally cut, shaped, and drilled in a fabrication shop as per the design
Carbon steel is produced as ingots, or flat plate or sheet. Until the 1960s carbon steels were produced with strengths up to X-52 (where X indicates the yield strength of carbon steel; X-52 means the yield strength of the carbon steel is 52,000 psi) (see section 3.4.2 for specification) and were delivered in the as-rolled or normalized condition. The process of controlled rolling was
Carbon and Low Alloy Steel Casting Mechanical PropertiesIn general, increasing the strength of a steel grade reduces its ductility. While most designers think in terms of the materials strength, most of the production of steel is in the lower strength grades, which have good ductility. Carbon content and heat treatment influence strength and ductility; shown in Figure 1. Carbon contents are typically

(~1200 MPa, or 180 ksi tensile strength), and then the scatter becomes too great to be reliable (Fig. 14.5). This does not necessarily mean it is wise to use as high a strength steel as possible to maximize fatigue life because, as the tensile strength increases, the fracture toughness de-creases and the environmental sensitivity increases.

Another result of extreme temperatures is that material will expand or contract in proportion to the temperature, due to physics. So when the temperature rises in a steel structure the atoms start to vibrate more and more.

The differences between stiffness and strength in metal
StrengthStiffnessAluminum Versus Steel in AutomobilesIssue No 15 - Grain Size and Material Strengthway to improve the strength of a material is to make the grains as small as possible, increasing the amount of grain boundary. Smaller grains have greater ratios of surface area to volume, which means a greater ratio of grain boundary to dislocations. The more grain boundaries that exist, the higher the strength becomes.
The influence of temperatures and strain rates on the Jan 01, 2015 · This study deals with the mechanical behavior of DP steel. A commercial dual phase steel (DP 800) was strained to 3.5% followed by annealing at 180 °C for 30 min to simulate the pressing of the plates and the paint-bake cycle involved in the manufacturing process of automobile body structures.The effect of temperature and strain rate on the mechanical behavior of this material was
Surface grinding with grit coarser than 180 and shot-blasting causes embrittlement at -100°C due to surface work-hardening, which, however, is corrected by annealing at 650-700°C for 1 h. This heat-treatment also provides a safeguard against the initiation of brittle fracture of welded structures by removing residual stresses.
