Nonlinear response history analysis (NRHA) is increasingly becoming more accessible and prevalent in research and practice. As the accuracy of the NRHA results depends on the ground motion characteristics and the robustness of the numerical model, research has focused on the development of guidance for performance-based seismic design and assessment...
A literature review and a computer study are conducted to identify
the requirements of finite element programs for the specific use of discrete
analyses of reinforced soil structures. The utility of six commercially
available programs are appraised with respect to the identified
requirements. The results of the study are directed...
One of the recent additions to the panoply of engineered wood products is cross-laminated timber (CLT). CLT is a prefabricated, large-scale, solid wood panel that consists of multiple layers of lumbers stacked together, with each layer arranged perpendicular to the next layer, glued with structural grade adhesives, and pressed. The...
Polymer modified asphalts have recently been the focus of much
attention in the U.S. due to claims that polymer additives will
lengthen the life of an asphalt pavement. Much of the published
research on this topic has been concentrated on the effects of
polymer modifiers on binder and mixture properties....
This report describes the hydrodynamic testing and
evaluation of a one-tenth scale model of the FMC Wave
Attenuation Device. The purpose of the test was to quantify
the wave attenuation characteristics and structural loading
induced by a test program of monochromatic incident waves
on the submerged structure. The device was...
The purpose of this investigation is to study the effect of the
solid transport capacity in pumping operation: A special type of
jet apparatus was investigated which emits a water jet downward
counter current to delivery flow, from inside of the suction pipe toward
sediment to be excavated. Two sizes...
The objectives of this study are to use SAP2000 to investigate lateral load paths and system behavior in a modular, light-frame wood structure by investigating different foundation configurations and to further develop and validate existing modeling techniques of shear wall elements based on the Perforated Shear Wall Method. The modeling...
Withdrawal from a two-layer flow field is examined in terms of
the degree of selectivity of the withdrawal flow and its dependence
on an ambient current. Selectivity is defined as the bias of withdrawing
one layer more strongly than the other; the extreme' case is
complete selective withdrawal, where one...
Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...
The author and compiler of Design Data for Field Engineers has
included in his volume short cuts in design, and miscellaneous data
and information used on general civil engineering projects from inception
to completion.
The book is intended for the engineer who may be stationed in
isolated areas and who...
