建筑物的一次噪音和二次噪音的区别
一次噪音：指的是由声源直接产生并传播到接收点的声音，是噪音的原始发声状态。比如建筑外部的交通噪声，像汽车行驶时的发动机声、轮胎与地面的摩擦声，以及建筑内部的人员活动声、设备运行的直接发声等，如空调外机运行时发出的声音，都属于一次噪音。 二次噪音：是一次噪音引起的次生噪音。当一次噪音的振动能量传递到建筑结构（如墙体、楼板等）后，使建筑结构产生振动，这种振动再向周围空气辐射出的声音就是二次噪音。例如，附近工厂机器运转产生的振动通过地面和建筑基础传至建筑结构，引发结构振动从而产生的噪音就属于二次噪音。

你能忍受无休止的噪声和振动吗？建筑物的振动与二次辐射噪声限值是多少？各方主体会有什么样的考量呢？
一、适用标准及区域分类 依据 JGJ/T 170 - 2009 标准，建筑区域分为五类： •0 类和 1 类：疗养区、高级宾馆区、文教区及机关、事业单位集中区域，以及住宅为主的私家区域，对环境振动噪声要求较高。 •2 类：居住、商业与工业混合区，规划商业区。 •3 类和 4 类：工业区或交通干线两侧区域。
别再忽视！建筑物振动不仅关乎法规，更影响你的生活体感！聊聊建筑物振动控制那些事儿！
你有没有过这样的经历：住在靠近轨道交通或工地附近，感觉房子时不时就跟着 “抖一抖”？这可不是小事，建筑物振动控制有着至关重要的意义，今天咱们就来深入聊聊。
2024 年台湾省花莲 7.4 级地震中隔震建筑的卓越表现与关键启示
在 2024 年 4 月 3 日，一场突如其来的强烈地震震撼了我国台湾省。此次地震发生于台湾时间 7 时 58 分 09 秒，矩震级达到 Mw 7.4，其震中位于花莲县政府东南偏南 25 千米处。花莲县和平乡遭受了极为强烈的震动，地震动峰值加速度（PGA）飙升至 363.7gal（0.37g），峰值速度也高达 65.7cm/s。花莲市同样未能幸免，PGA 达到 458gal（0.47g）、PGV 为 56.3cm/s。而太鲁阁站更是记录到南北向最大 PGA 高达 1491gal（1.52g），如此强烈的地震动在台湾省东北至中西部的 14 个站点都检测到了近断层脉冲型地震动，其影响范围之广、震动强度之大，给当地带来了巨大的挑战。
日本隔震建筑的抗震卓越表现：地震观测记录下的稳固防线
在地震频发的日本，隔震建筑已成为守护生命与财产安全的关键力量。自 1995 年阪神地震的沉痛教训后，隔震技术在这片土地上蓬勃发展，如今，数量已超 5000 栋，若将独户住宅纳入统计，更是突破 10000 栋之多。这些建筑类型丰富多样，办公楼、公寓、医院及独户住宅等都广泛应用了隔震技术，工程师们巧妙组合各类隔震装置，像是橡胶支座、滑动支座、滚轴支座、滞回阻尼器、油压阻尼器等，如同为建筑精心打造了一套坚固的抗震铠甲，力求在地震来临时将灾害影响降至最低。
演唱会致周边居民房屋“摇晃” ——震安“震振双控”产品，您值得拥有！
“在我们的周边，有我们亲爱的左邻右舍，真的感受到了地震！” 昨日（11月19日），五月天“回到那一天”演唱会继续在上海体育馆举行。开场阶段，五月天主唱阿信告诉现场歌迷，在他们举行演唱会期间，周边居民家中感受到了“地震”，他呼吁歌迷“以挥手代替跳跃”。

Solutions of Seismic isolation and Energy dissipation
QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) is a full solution and full life-cycle service provider of seismic isolation and Shock absorption(Energy dissipation) technology. Founded in January 2010, SAFETYINSIDE Is a high-tech enterprise, technology demonstration center and academician Zhou Fulin workstation in the industry. In March 2019, SAFETYINSIDE was successfully listed in Shenzhen Stock Exchange A shares (stock code: SZ300767), and was selected into the Ministry of Industry and Information Technology's first batch of "little giant" enterprises list, becoming a national manufacturing "single champion" and service-oriented manufacturing demonstration enterprises.
Company Profile：Introduction to well-known seismic isolation company in China
Seismic isolation and Shock absorption(Energy dissipation) technology is one of the most important innovation technologies in the field of earthquake prevention and disaster prevention engineering in the last 50 years. It protects the building itself and the lives and property of the occupants more effectively by isolating or consuming seismic energy in a soft way. QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) is a full solution and full life-cycle service provider of seismic isolation and Shock absorption(Energy dissipation) technology. Founded in January 2010, SAFETYINSIDE Is a high-tech enterprise, technology demonstration center and academician Zhou Fulin workstation in the industry. In March 2019, SAFETYINSIDE was successfully listed in Shenzhen Stock Exchange A shares (stock code: SZ300767), and was selected into the Ministry of Industry and Information Technology's first batch of "little giant" enterprises list, becoming a national manufacturing "single champion" and service-oriented manufacturing demonstration enterprises. QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) has participated in almost all the relevant technical standards of the Chinese industry (nearly 60 norms), and the enterprise standards have been gradually transformed into national, local and industrial standards. QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) products have been widely used in schools, hospitals, large commercial complexes, stadiums, museums, emergency command centers, nuclear power plants, airports, LNG storage tanks, new residential buildings and old building reinforcement and other flexible seismic fields. QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) has participated in more than 20,000 building isolation and Shock absorption(Energy dissipation) projects, ranking first in a single institution in the world. Among them, we undertook the Beijing Daxing International Airport terminal project, the first of the "Seven wonders of the New World". This projrct has become a new benchmark in the global shock reduction industry. The same isolation bearing product is collected in the National Museum of China.QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE)is the industry leader in China and a leading provider of complete seismic isolation andShock absorption(Energy dissipation) solutions worldwide. Now,QuakeSafe Technologies Co., Ltd. (Brand: SAFETYINSIDE) is actively exploring the global market. We hope to work with more partners to build safer buildings in earthquakes and benefit the people with the power of science and technology. Life matters ! Make the world safer！ Looking forward to cooperating with you! Seismic base isolation, also known as base isolation,or base isolation system,is one of the most popular means of protecting a structure against earthquake forces.It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus protecting a building or non-building structure's integrity. Common seismic isolation devices for buildings include： seismic bearing / seismic isolator / quake isolator / rubber bearing /Liner natural rubber bearing / lead rubber bearing /high damping rubber bearing/laminated rubber isolation bearing /elastic sliding bearing / friction pendulum bearing...... Their abbreviations are: LNR/LRB/NRB/ESB/HDR/ESB/FPS/FPB......
