This study investigates the effectiveness of tuned mass dampers (TMDs) in controlling vibrations in low-rise reinforced concrete buildings. It examines both linear and nonlinear behaviors of concrete structures subjected to strong ground motions from the PEER database. The research follows the ASCE 7-16 provisions to model structural nonlinearity....

Centrifugal tests provide an efficacious experimental process to predict the behavior of deep excavations, and numerical models are indispensable for demonstrating the test results and analyzing the engineering demand parameters. Uncertainty in material properties can cause simulations to differ from tests; therefore, updating the model becomes ine...

The base isolation (BI) device is widely used for reducing seismic energy transmitted to the upper part of the structures. The rubber property of lead rubber bearing (LRB) BI devices degrades with time and environmental conditions, affecting the controlling performance of BI devices. This study investigates the degradation of capacity of base-isola...

This paper describes a newly developed tool, called FeView, which is a Python-based graphical user interface (GUI) for OpenSees solver. FeView offers an open-source and stand-alone windows system that is very easy and simple to use. It can support a wide range of element types (46 types) and all kinds of material, connection, constraint, analysis o...

The determination of the damage index to reveal the performance level of a structure can constitute the seismic risk generalization approach based on the parametric analysis. This study implemented this concept to one kind of civil engineering structure that is the concrete gravity dam. Different cases of the structure exhibit their individual resp...

Determination of reliability-index has been handled by the site seismic hazard analysis with the help of PSHRisk-tool (developed by the authors) and risk assessment. Incorporated with the unc...

This paper investigates the performance of tuned mass damper (TMD) and dynamic behavior of TMD-controlled concrete structure considering the ground motion (GM) characteristics based on frequency content. The effectiveness of TMD in reducing the structural response and probability of collapse of the building frames are affected by the frequency char...

This study is to evaluate the seismic capacity of the fire-damaged cabinet facility in a nuclear power plant (NPP). A prototype of an electrical cabinet is modeled using OpenSees for the numerical simulation. To capture the nonlinear behavior of the cabinet, the constitutive law of the material model under the fire environment is considered. The ex...

During the construction of the various structures, soil strength plays a vital role in structural performance. Hence, soil improvement techniques are needed to improve the soil strength as well. This study aimed to improve shear strength of sandy soil using granulated waste glass (GWG) and microsteel fiber (MSF). In order to apply this idea, there...

Concrete gravity dam is one of the most important infrastructures for a country. The failure of dam structure due to earthquake affects seriously the surrounding environment, especially in human life. Therefore, the risk assessment of these dams is very important to understand the operant condition of the structure. During the entire service time o...

Reliability assessment is used for decisions making about the acceptability of an existing structure. In this study, the seismic response of Bohyeonsan concrete gravity dam is analyzed using the 2D Finite Element Model (FEM) that is developed by ABAQUS. The calibration of the FEM of this dam is carried out using the Response Surface Methodology (RS...

The study of the hydraulic conductivity (K) for flow of water through permeable soil media is important in soil mechanics. It has been recognized that K is statistically related to the grain-size distribution. A series of permeability test were conducted on five types granular soil (denoted by S-1, S-2, S-3, S-4 and S-5) taken from different locati...

Soils from Barind tract have been investigated to finding out their geotechnical properties and determine the possible variations between them. Three types of soil samples has been collected from Godagari, Tanore and Kakonhat and they were subjected to a number of geotechnical tests in the laboratory. Then the obtained values were subsequently subj...

In this research shear strength behavior of soil is investigated which is an important aspect in many geotechnical engineering problems such as the bearing capacity of shallow foundations, the stability of the slopes of dams, embankments & hills and lateral earth pressure on retaining walls with presence of marble dust. For identifying the shear st...

Abstract— In this paper the waste materials like SWA as partial replacement of cement and GP as partial replacement of sand is used in concrete. Here these materials are used as a varying percentage to observe the effect of concrete compressive strength. At first the concrete is mixed with 2%, 4%, 6%, 8% and 10% SWA, keeping constant 5% GP. Then, o...
