1、地震是怎么作用的,轰动怎么对建筑形成侵害
  1. How do earthquakes work and how do sensations damage buildings?
  首先,咱们需求晓得什么是地震。凭据百度百科的解说,咱们不妨获悉,地震是地壳释放能量的过程中形成的振动,经过地震波对人类的生存形成影响甚而毁坏。
  First, we need to know what earthquakes are. According to Baidu Encyclopedia's explanation, we may as well learn that earthquakes are the vibration formed in the process of releasing energy from the earth's crust, and even destroy the survival of human beings through seismic waves.
  那么地震波又是什么呢?根据目前天下研讨地震的水平,地震波不妨分为纵波(P波)、横波(S波)、和面波(L波)三种模式。纵波属于推进波,使地面发生上下的轰动,毁坏性相对较弱。横波属于剪切波,使地面发生前后控制的颤动,毁坏性较强。面波属于纵波和横波在地表相遇后激励发生的夹杂波,毁坏性对照强。
  So what is seismic wave? According to the level of earthquakes studied in the world, seismic wave can be divided into three modes: P wave, S wave and L wave. P-wave belongs to propulsive wave, which makes the ground stir up and down, and its destructiveness is relatively weak. Shear wave belongs to shear wave, which makes the ground tremble before and after control, and is more destructive. Surface wave is a kind of inclusion wave which is stimulated by P-wave and S-wave after they meet on the surface, and it has a strong destructive contrast.
  在机电工程抗震界限,普通的理解成:重力支吊架起到抵抗、缓和垂直地震力(即纵波)的作用。而抗震支吊架,经过其特殊的斜撑结构,大大的抵抗和缓和水平地震力(即横波)的作用。
  The seismic limit of electromechanical engineering is generally understood as: gravity support and suspension play the role of resisting and mitigating vertical seismic force (i.e. longitudinal wave). The anti-seismic brace and hanger, through its special brace structure, greatly resists and mitigates the effect of horizontal seismic force (i.e. shear wave).

  2、抗震支吊架作用方法,抗震斜撑怎么抵抗水平地震力
  2. The method of action of anti-seismic braces and suspensions, and how anti-seismic diagonal braces resist horizontal seismic forces
  咱们都晓得,抗震支吊架是经过抗震斜撑的加固,来起到抗震的作用。
  As we all know, the anti-seismic brace and hanger is reinforced by the anti-seismic diagonal brace to play an anti-seismic role.
  正是由于抗震斜撑的存在,才能使得原来在水平目标上毫无约束的管道支吊架体系可以在地震发生时做到平安可靠,预防管道支吊架体系垮塌掉落,形成要紧的次生灾害。
  It is precisely because of the existence of anti-seismic diagonal braces that the original unconstrained pipeline support and hanger system on horizontal targets can be safe and reliable in the event of earthquakes, prevent the collapse and fall of pipeline support and hanger system, and form important secondary disasters.
  3、斜撑的抗震作用与承载重力有否关系,斜撑上是否有重力作用
  3. Whether the anti-seismic action of braces is related to the bearing gravity and whether there is gravity action on braces?
  由 2点咱们不妨晓得,抗震斜撑在力学上,有肯定的重力荷载效应。当然,管道支吊架体系所承载的重力越大,抗震斜撑上接收的重力效应值也越大,所以斜撑的抗震作用与承载重力着实存在肯定的关系。
  From two points, we may know that seismic braces have definite gravity load effect in mechanics. Of course, the greater the gravity of the pipeline support and suspension system, the greater the gravity effect value received on the seismic brace, so there is a positive relationship between the seismic effect of the brace and the bearing gravity.
  可是,有一点咱们需求关注,抗震支吊架的性能性主若是“抗震”,而非“承载”。抗震支吊架安装的条件是,重力支吊架一定符合条件,可以满足垂直目标上全部管道及介质等因素的重力作用,即不研究抗震支吊架上的重力作用也能满足性能需求。普通的说,不妨概括成:抗震斜撑上有重力作用,可是咱们在进行设计和计算时,暂不研究抗震支吊架的重力效应,即不研究重力共架。(特例除外,某些空间眇小的地方可能会出现重力共架的状况。)
  However, one thing we need to pay attention to is that the performance of the anti-seismic support and hanger is mainly "anti-seismic" rather than "bearing". The installation condition of the anti-seismic support and hanger is that the gravity support and hanger meet certain conditions, and can satisfy the gravity effect of all pipelines and media on the vertical target, that is, the gravity effect on the anti-seismic support and hanger can also satisfy the performance requirement without studying the gravity effect on the anti-seismic support and hanger. Generally speaking, it can be summarized as follows: seismic braces have gravity effect, but we do not study the gravity effect of seismic braces and suspensions, that is, gravity common braces. (Except for special cases, gravity co-shelf may occur in some places with small space. )
