Composite floor system utilizing asymmetric H-shaped steel to mitigate the problem of floor height, one of the most serious drawbacks inherent in composite steel structures boasts advantages such as increase in floor area up to 10%, economy in building materials and resources and reduction in wastes. [1] However, before it is commercialized and actually used in the field, studies on the long-span structure of composite floor system having the advantage of reduced floor height should be conducted to define its rapid deformational behavior upon a fire and find ways to secure fire-resistance performance, which was why this study was carried out.

All sciences, which are related to the engineering, use widely sensors, in their applications[1-3].
For this reason, it is indispensable and necessary, firstly to carry out a simulation that can calculate at any point in spacecraft any kind of magnetic field (AC or DC), which is produced by electric dipoles generated by electric equipment (eventually by heating them) or by magnetic dipoles, as the result of hard or soft magnetic materials.
Magnetometers that are based on magnetic materials and magnetic effects, such as the magneto-resistance effect, the magneto-impedance effect and inductive techniques manage to measure small field variation or field gradient.

Introduction Nanoscale materials exhibit unique physical and chemical properties that are different from their bulk properties [1].
This opens the way to the search for novel magnetic materials that could be applied to nano-spintronics and ultrahigh-density storage devices [2].
Ferromagnetic nanoparticles are considered to be the key materials from a viewpoint of the application for ultrahigh-density magnetic storage media.
