使用 SkyCiv 负载生成器 – 协会 7-16 建筑物的地震荷载计算

SkyCiv introduces the seismic load calculation for buildings using ASCE 7-16 Equivalent Lateral Force procedure. In addition to the parameters for wind and snow loads, the seismic load calculation uses seismic parameters obtained from U.S. Geological Survey (USGS) Web Services. Users will get the following data that can be modified to get the most appropriate seismic load for the structure:

  • Long-period transition period \( {Ť}_{大号} \)
  • Design spectral response acceleration parameter at short period, \( {小号}_{DS} \)
  • Design spectral response acceleration parameter at 1s period, \( {小号}_{D1} \)
  • Mapped maximum considered earthquake spectral response acceleration parameter, \( {小号}_{1} \)

Free users will be able to get these data but will only be able to calculate the seismic loads for a maximum of 3 每天解决. 用 专业帐户或通过购买 独立的Load Generator模块, 你可以使用所有的功能 这个计算只要你想要. 您可以通过此购买独立模块 链接.

网站数据

Together with the wind speed and ground snow load data, users can get the seismic parameters for the location obtained from USGS Web Services by defining theSite Classfirst and then the location:

USGS Seismic Parameters

数字 2. Site seismic parameters from USGS Web Services.

Users can modify the parameters obtained from USGS Web Services to obtain the most appropriate seismic load for the structure.

结构数据

To calculate the seismic load for the structure, the structure data should be filled. 此外, 的 required site seismic parameters in Site Tab should have values defined. 我们将通过计算地形因子来讨论地形对结构风荷载的影响: \( {Ť}_{大号} \), \( {小号}_{DS} \), \( {小号}_{D1} \), 和 \( {小号}_{1} \). By meeting these conditions, you can check theCalculate Seismic Load” 复选框.

Seismic data  of the structure

数字 3. Seismic parameters of the structure.

The seismic parameters needed to be defined are the following:

  • Structure systemfor determining the values of \({C}_{Ť} \) 和 \(X \) which will be used in calculating the approximate fundamental period of the structure \({Ť}_{一个} \)
  • Approximate fundamental period of the structure \({Ť}_{一个} \) – can be user-defined to more appropriate seismic load calculation
  • 响应修正因子 \( [R \) – default value is 8.5 and be modified for more appropriate seismic results
  • Redundancy factor, \( ρ \) – default value is 1.0 and can be modified. Used in diaphragm forces calculation
  • Floor Weightsused for the vertical distribution of base shear and for diaphragm forces. Data per level required are: 我们已经可以解决设计风速 (for designation), 海拔, and Weight

The approximate fundamental period of the structure is automatically calculated as guide for the users when the Structure system dropdown is changed. Users are free to edit this value which is affect the corresponding calculated base shear for the structure.
