FORMULAS AND CHARTS FOR IMPEDANCES OF SURFACE AND EMBEDDED FOUNDATIONS Abstract A complete set of algebraic formulas and dimensionless charts is presented for readily computing the dynamic stiffnesses (K) and damping coefficients (C) of foundations harmonically oscillating on/in a homogeneous half‐space. All possible modes of vibration, a realistic range of Poisson's ratios, and a practically sufficient range of oscillation frequencies are considered. The foundations have a rigid basema ...اصل و ترجمه مقاله لاتین A MACRO-ELEMENT FOR DYNAMIC SOIL-STRUCTURE INTERACTION ANALYSES OF SHALLOW FOUNDATIONS
A MACRO-ELEMENT FOR DYNAMIC SOIL-STRUCTURE INTERACTION ANALYSES OF SHALLOW FOUNDATIONS Abstract The scope of the paper is to present some aspects of the development of a "macro-element" for dynamic soil-structure interaction analyses of shallow foundations. Initially the concept of "macro-element" is introduced and is illustrated with the aid of a very simple example originating from structural engineering. Then the link is made with the modeling of the dynamic response of shallow foundat ...اصل و ترجمه مقاله لاتین Soil-Structure Interaction for Building Structures - Chapter 2 :Inertial Interaction
Soil-Structure Interaction for Building Structures - Chapter 2 :Inertial Interaction Inertial interaction refers to displacements and rotations at the foundation level of a structure that result from inertia-driven forces such as base shear and moment. This chapter describes inertial soil-structure interaction effects. Inertial displacements and rotations can be a significant source of flexibility and energy dissipation in the soilstructure system. Section 2.1 discusses system behavior and high ...اصل و ترجمه مقاله لاتین Seismic active pressure distribution history behind rigid retaining walls
Seismic active pressure distribution history behind rigid retaining walls Abstract Evaluating the seismic active earth pressure on retaining walls is currently based on pseudo-static method in practices. In this method, however, it is not simple, choosing an appropriate value for earthquake coefficient, which should fully reflect the dynamic characteristics of both soil and loading is an important problem. On the other hand, by using only two extra dynamic parameters that are shear wave velocit ...اصل و ترجمه مقاله لاتین Evaluation of the Use of Steel Bracing to Improve Seismic Performance of Reinforced Concrete Building
Evaluation of the Use of Steel Bracing to Improve Seismic Performance of Reinforced Concrete Building Abstract The aim of this paper is to evaluate the possible improvement of seismic performance of existing reinforced concrete building (the 5th Building of UNS Engineering Faculty) by the use of steel bracing. Three methods of seismic evaluation are employed for the purpose of the study i.e. Nonlinear Static Pushover Displacement Coefficient Method as described in FEMA 356, Improvement of ...اصل و ترجمه مقاله لاتین Bio-nanocomposites for food packaging applications
Bio-nanocomposites for food packaging applications Abstract There is growing interest in developing bio-based polymers and innovative process technologies that can reduce the dependence on fossil fuel and move to a sustainable materials basis. Bio-nanocomposites open an opportunity for the use of new, high performance, light weight green nanocomposite materials making them to replace conventional non-biodegradable petroleum-based plastic packaging materials. So far, the most studied bio-nanoco ...اصل و ترجمه مقاله لاتین Effect of ohmic treatment on quality characteristic of meat: A review
Effect of ohmic treatment on quality characteristic of meat: A review Abstract Ohmic cooking, a well-known electro-heating technique, provides an alternative method for cooking meat products due to its ability for rapid heat generation. Ohmic heating uses the resistance of meat products to convert the electric energy into heat. The rate of heat generation depends on the voltage gradient applied and the electrical conductivity of the meat product. The advantages of ohmic cooking over conventiona ...اصل و ترجمه مقاله لاتین Decontamination by ultrasound application in fresh fruits and vegetables
Decontamination by ultrasound application in fresh fruits and vegetables Abstract Changes in consumer eating habits, health concerns, and convenient and practical foods have led to an increased demand for fruit and vegetable products. Food safety is essential considering that there are reports of outbreaks involving the consumption of fruits and vegetables contaminated with pathogens. Washing associated with sanitizer procedure is considered as a critical step to satisfy hygienic and sanitary r ...پروژه کنترل تطبیقی مدل مرجع با داکیومنت لاتین و توضیحات فارسی (پروژه criuse) مناسب درس کنترل تطبیقی
