Railroad Tie Lateral Resistance on Open Deck Plate Girder Bridges
… such as hook bolts. These fasteners provide lateral resistance for the bridge ties. Currently there are no provisions to assist in the calculation of lateral resistance provided by railroad ties on open-deck bridges, and as a result there are no specific requirements for the spacing of deck …

Determination of Lateral Resistance of Deck Tie Fasteners in Smooth Top Bridge Girders
… preliminary design aids for the determination of lateral resistance capacity and spacing requirements of deck tie fasteners in curved railroad bridges with smooth top girders. In railroad bridge design, required lateral resistance dictates the spacing of deck tie fasteners. Currently, no …

Examination of the Lateral Resistance of Cross-Laminated Timber in Panel-Panel Connections
… The viability of CLT as an element to resist lateral forces from racking has been of great interest (Dujic et al. 2004, Blass and Fellmoser 2004, and Moosbrugger et al. 2006). However, most research to date has been conducted on full-scale wall panels connected with proprietary fasteners …

Evaluation of structural systems for mass timber buildings in low to moderate seismic regions
… of multi-story mass timber structures and their lateral systems in low to moderate seismic regions. Boston, MA has been chosen as the location for a feasibility analysis of 8-, 12-, and 18- story mass timber structures. These building prototypes are used to compare the structural and …

Full-Scale-Lateral-Load Test of a 1.2 m Diameter Drilled Shaft in Sand
… interaction models associated with laterally loaded deep foundations have typically been based on load tests involving relatively small diameter foundations. The lateral soil resistance for larger diameter foundations has been assumed to increase linearly with diameter; however, few, …

Seismic Design Studies of Low-Rise Steel Frames
… with steel moment-resisting frames providing the lateral resistance for strong ground motions was examined. The inelastic behavior of frames is dependent on several parameters such as design base shear, beam-to-column strength ratio, moment-resisting connection behavior, nonstructural element …

A Shapely Resistance: A Study in Construction for a Kindergarten
… The roof is vaulted and the walls are curved for lateral resistance and in order to make folds scaled to a child. These physical moves work towards the theme of the Kindergarten: a place for the transition between home and school.

Dynamic response of URM buildings with flexible diaphragms
… there is an ever-increasing need to evaluate the lateral resistance of existing structures. Unreinforced masonry (URM) structures are perceived to be seismically unsafe due to dramatic media coverage of these structures following earthquakes. However, well-built URM structures can possess …

Computational fluid dynamics modelling of pipeline on-bottom stability.
… hydrodynamic loads on pipeline and soil resistance in isolation. In reality, the pipeline stability problem is much more complex involving hydrodynamic loadings, pipeline response, soil resistance, embedment and pipe-soil-fluid interaction. In this thesis Computational Fluid Dynamics …

Implementation of an anisotropic plasticity model and its application to pile foundations problems
… behaviour of pile foundations under vertical and lateral load combinations has been the subject of numerous studies, the response under combined horizontal and torsional loading has received considerably less attention. The emphasis of this research is on using numerical simulation to investigate …

Reavaliação de método semi-empírico de previsão de capacidade de carga de estacas a partir de banco de dados
… the study of the use of other SPTs for the point resistance besides those initially proposed by the method, trying to consider failure models proposed in the bibliography, as well as correlations between cone and SPT recommended by other authors. It was also analysed loading tests on instrumented, …

Full Scale Static Lateral Load Test of a 9 Pile Group in Sand
… has been done to study the effects of spacing in laterally loaded pile groups and how the pile spacing affects lateral resistance of the piles. In this test a 9-pile group of steel piles was installed in a 3x3 configuration in sand. The piles were spaced from center-to-center at a distance of 5.65 …

Hybrid damping system for high-rise building outriggers
… utilizes different strategies to mitigate the lateral displacement and acceleration from wind and earthquake excitation. One of the strategies is to dissipate external energy with dampers. For high-rise buildings, outrigger systems which connect the core and perimeter columns are innovative …

Impact of cladding on mid-rise buildings in the Northridge Earthquake
… interacts with the structural frame in providing lateral resistance. The advantages and disadvantages of different cladding materials, cladding systems, and cladding connections are presented in this thesis. The effects of cladding on mid-rise buildings in the Northridge Earthquake in the Los …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
… soil strength of only 6-8 psi (850-1150 psf). Lateral loading of the pile foundation was then performed on these foundations. The results of this test were compared with a similar test performed on the same foundations under native soil conditions. The total lateral capacity of the pile …

An Investigation of Nailed Connection Performance in a Cyclic Humidity Environment
… connection samples were tested for lateral resistance following various periods of moisture exposure. Elastic stiffness, 5% offset yield load, maximum yield load, and failure yield were computed and analyzed using the data collected. The parameters were compared among connection …

Investigation of the Resistance of Pile Caps to Lateral Loading
… buried, would be expected to provide significant resistance to lateral loads. However, practical procedures for computing the resistance of pile caps to lateral loads have not been developed, and, for this reason, cap resistance is usually ignored. Neglecting cap resistance results in estimates of …
