This thesis evaluates and verifies a numerical method proposed to simulate roof snow drifts. The verification process entails a quantitative comparison of the analytical predicted drift size with data procured from a ...

Drifted snow loads on multilevel flat roofed structures account for a large percentage of the building roof losses in the United States, yet little information is presently available which quantitatively describes the ...

Thirty inch nominal diameter reinforced concrete pipelines, having standard rubber gasketed bell and spigot joints, were tested in our laboratory at Rensselaer. The joint characteristics of interest were the force deformation ...

In this dissertation, the negative stiffness devices are described along with their hysteretic behavior as obtained from a series of cyclic tests which were utilized to calibrate the parameters of a numerical model. In ...

While understanding of external flows and pressures for tornadoes are improving, internal pressure behavior remains elusive. This study was performed with the intention to observe how internal pressures change as a tornado ...

Recent experimental testing of a full-scale building, with dampers installed in toggle type displacement amplification frames, was conducted as part of the NEES-Soft Project and demonstrated that this type of energy ...

Freezing starts when water molecules within the concrete pores reach their freezing temperature and begin to solidify. Conversely, thawing is the melting of the newly-formed ice molecules at high temperatures. This cycle ...

One of the primary concerns in structural engineering is the prediction of response of concrete structures under various environmental and loading conditions. The accurate prediction of the mechanical behavior of concrete ...

In this research, a detailed procedure for effective calibration was introduced by decoupling the different phenomena in the experimental tests during the calibration process. This procedure maximizes the robustness of the ...
