Ensoft DynaN 3.0.13-AMPED

DYNAN基于改进的Novak方法,其中在近场和远场之间形成非反射边界以解释边界中的土壤质量。该程序在谐波,瞬态和随机加载下产生浅层和深层地基的动态响应。这种装载可以通过旋转或往复机械,地震,风,爆炸,海浪和其他来源产生。

基础(或桩上的顶盖)被假定为刚性的,并且所有六个自由度被认为是耦合的。基础刚度和阻尼常数也可以用于土 – 结构相互作用分析。

支撑土的刚度和阻尼常数以及地表基础,嵌入式基础和桩基的程序中分析和评估所需的阻尼常数。土层,地基周围可能存在的弱化区(见草图)和桩 – 土 – 桩相互作用都被考虑在内。

该计算方法已应用于重要的工程实践(Han,1987,Han等,1999)。为了研究土壤 – 结构相互作用,对全尺寸垫基础(Han,1989)和全尺寸桩(Han和Novak,1989,1992)进行了一系列动力学实验。来自地基振动的弹性波能量作为辐射阻尼在三维中消散。理论中假定土壤不是理想的弹性介质,实验表明在计算过程中高估了阻尼。出于实用目的,基于实验结果,DYNAN中的阻尼减小。

DYNAN可用于时域瞬态和随机加载下的动态分析。它也可以用于频域中的谐波加载。通过子结构方法,利用SAP2000等有限元程序计算出上部结构的动力响应,并利用DYNAN程序生成地基的刚度和阻尼。

DYNAN is based on the improved Novak’s method where a non-reflective boundary is formed between the near field and the far field to account for the mass of soil in the boundary. The program yields the dynamic response of both shallow and deep foundations under harmonic, transient, and random loadings. Such loadings can be produced by rotating or reciprocating machines, earthquake, wind, blast, sea waves, and other sources.

The foundations (or caps on piles) are assumed to be rigid, and all six degrees of freedom are considered as coupled. The foundation stiffness and damping constants are also returned for possible use in soil-structure interaction analysis.

The stiffness of the supporting soil along with damping constants needed for the analysis and evaluated in the program for surface foundations, embedded foundations, and pile foundations. Soil layering, a possible weakened zone (see sketch) around a foundation, and pile-soil-pile interaction are all taken into account.

The computational method has been applied to important engineering practice (Han, 1987, and Han, et al, 1999). To investigate soil-structure interaction, a series of dynamic experiments were performed on full-scale mat foundations (Han, 1989) and on full-scale piles (Han and Novak, 1989, 1992). The elastic wave energy from foundation vibration was dissipated in three dimensions as radiation damping. The soil is not a perfect elastic medium as assumed in the theory and the experiments showed that damping is overestimated in the computation. For practical purposes, the damping is reduced in DYNAN based on experimental results.

DYNAN can be used for the dynamic analysis under transient and random loading in the time domain. It also can be used for harmonic loading in the frequency domain. By means of a substructure method, the dynamic response of superstructure is calculated using a finite element program, such as SAP2000, and the stiffness and damping of foundation are generated using the DYNAN program.

FEATURES

  • The program employs well-established analytical solutions for soil-structure interaction under dynamic loading conditions.
  • Analyze four different foundation types
    • footing supported on a homogeneous half-space (halfspace)
    • footing supported on homogeneous layer (stratum)
    • footing embedded in layered medium (multilayer)
    • deep foundation (pile option)
  • Developed based on the improved Novak method and a non-reflective boundary is formed between the near field and the far field to account for the mass of soil in the boundary zone.
  • For practical design purposes, the foundations (or caps on piles) are assumed to be rigid, and all six degrees of freedom are considered as coupled.
  • The group effect of piles is accounted for by using the method of interaction factors in the DYNAN program.
  • Analyze response due to constant amltitude or frequency dependent (quadratic) harmonic excitation
  • DYNAN can be used for the dynamic analysis under transient and random loading in the time domain (see Han and Cathro, 1997). It also can be used for harmonic loading in the frequency domain.
  • The program generates the output data for each frequency of harmonic loads on the foundation.
