Problems solved by technology

At present, it is not possible to fully check and calculate the deformation and stress modes of structures under earthquakes in the world.
[0004] At present, there are many studies abroad on the seismic performance of steel bars and steel plates, but there is no standard formulation and research on seismic H-beams.

Embodiment Construction

[0016] The technical solutions of the present invention will be described in detail below with reference to exemplary implementations. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

[0017] From the perspective of sustainable social development, the traditional production methods of brick-concrete and reinforced concrete structures can no longer meet the needs of building development, and the steel structure system has the advantages of facilitating the realization of standardization, componentization, industrialization, integration of production and operation, and energy saving. , water-saving, land-saving, material-saving, reusable and other characteristics, fully demonstrates the charm of "conservation-oriente...

Abstract

The invention discloses Q390KZ vibration-resistance hot-rolled H profile steel for a steel structure. The H profile steel comprises the following chemical components in percentage by mass: 0.16-0.18% of C, 0.55-0.58% of Si, 1.5-1.7% of Mn, 0.035% or less of P, 0.035% or less of S, 0.04-0.07% of Nb, 0.16-0.18% of Ti, and the balance of Fe element. The invention further discloses a preparation method of the Q390KZ vibration-resistance hot-rolled H profile steel for the steel structure. The H profile steel enables the material to achieve excellent welding performance and low-temperature impact resistance.

Description

technical field [0001] The invention relates to a metallurgical material technology, in particular to a Q390KZ shock-resistant hot-rolled H-shaped steel for steel structures and a preparation method thereof. Background technique [0002] Earthquake is a serious natural disaster faced by human society. According to statistics, an average of about 5 million earthquakes occur on the earth every year, of which destructive earthquakes of magnitude 5 or above account for about 1,000. Earthquakes usually bring huge economic and property losses to human beings, and their impact is long-lasting. Earthquake events are sudden and short in duration, which can cause casualties and damage to facilities within a few seconds. [0003] The current status of space structure design at home and abroad is: generally only static analysis is done, and dynamic time-history response analysis is also done for major structures, but most of them are limited to linear analysis, the influence of initia...
