Floor Vibrations: Girder Effective Moment of Inertia and Cost Study
Studies on the effective moment of inertia of girders that support concrete slabs using joist seats as the horizontal shear connections, and a cost efficiency analysis comparing composite and non-composite floor systems that meet vibrations design standards, were conducted. The first study was …

A Study Of Effective Moment of Inertia Models for Full-Scale Reinforced Concrete T-Beams Subjected to a Tandem-Axle Load Configuration
This thesis is a product of the U.S. Army Corp of Engineer's desire to develop a more accurate procedure for estimating the load capacity of an in-service T-beam bridge. A bridge type that is a stumbling block for U.S. Army field engineers due to the unknown amount and placement of the flexural …

Vibration and Flexural Strength Characteristics of Composite Castellated Beams
With the development of lightweight concrete and design optimizations, floor vibration problems are becoming a serious serviceability problem. The castellated beam is a prime example and was the focus of this study. The vibration and flexural strength performance were verified in this paper. The …

Fundamental Natural Frequency of Steel Joist Supported Floors
… in determining the first natural frequency of steel joist supported floors were studied. The aspects are: 1) determining which finite element model best predict the behavior of joist-slab tee-beams, 2) investigating the ability of proposed equations to calculate the effective moment of …

Vibration characteristics of joist and joist-girder members
With the development of lightweight steel beam and steel joist-concrete slab floor systems, floor vibration problems are becoming more and more prevalent. This paper presents the experimental and analytical study of the vibration characteristics of steel joist and joist-girder members. Three …

Investigation of several aspects of the vibration characteristics of steel member-supported floors
… influencing the vibration characteristics of steel member supported floors were investigated. The four aspects are: 1) the number of tee-beams effective in resisting a heel-drop impact for steel joist and steel beam-concrete slab floors, 2) the effective moment of inertia of steel joist and …

The Quantum Mechanical Hamiltonian of Rotating-Vibrating Polyatomic Molecules and an Exact Solution
… is obtained using well-established techniques of differential geometry. The difficulties and the ambiguities in the traditional approach to this problem--that of quantization--are then investigated. In this unified treatment of linear and nonlinear molecules, the reasons that previously have …

Feasibility Study Of Evaluating Durability Of Cfrp-strengthened Beams Using In-situ Load Test
In Florida a number of highway bridges were retrofitted on their reinforced concrete (RC) girders with carbon-fiber reinforced polymers (CFRP) during the 1990's. Their conditions, after being in service for approximately 10 years, are of significant interest to the State's highway authority, as …

Path Integral Monte Carlo Simulations of Helium: From Superfluid Droplets to Quantum Crystals
… for calculating the equilibrium properties of quantum systems at finite temperature. We have achieved linear scaling of computer time with number of particles through the use of neighbor lists, allowing us to simulate systems of several thousand atoms. We have derived a local superfluid …

Modelling of reinforced concrete slab deflections at service loading
… under service loading is an important aspect of reinforced concrete slab design. Under-design can cause large deflections which can be expensive to repair, if at all possible. Over-design can lead to material wastage and unnecessary dead load. Deflection is inversely proportional to the …
