Assessment of Analytical Procedures for Designing Metal Buildings for Wind Drift Serviceability
While designing metal buildings for wind drift, for simplicity of analysis and design, connection at base of column is considered as pinned which provides no rotational restraint. The actual behavior of the connection however, is partially rigid, that provides some rotational stiffness even in case …

Wind Drift Design of Steel Framed Buildings: An Analytical Study and a Survey of the Practice
… must take into consideration the lateral drift of the structure due to wind loading and any serviceability issues that may arise from this lateral movement. This thesis focuses on one of these issues, damage to nonstructural components. Although there are no specific requirements in the …

Laboratory Test Program of Rotary Plate Sprinklers
… crop and is influenced by evaporation losses, wind drift, runoff and deep percolation. Application uniformity measures the evenness of the water application over the irrigated area. Sprinkler characteristics that influence application efficiency and uniformity include:<br> • Wetted diameter - …

Rational Procedure for Damage Based Serviceability Design of Steel Buildings Under Wind Loads and a Simple Linear Response History Procedure for Building Codes
… two topics: the development of a procedure for wind serviceability design of steel buildings and the development of a simple linear response history analysis for building codes. In the United States the building codes are generally silent on the issue of serviceability. This has led to a wide …

Structural Optimization using the Principle of Virtual Work and an Analytical Study on Metal Buildings
… column base connection as partially rigid has on wind drift in metal building frames. Before beginning the study, a literature review was conducted on the rotation stiffness provided by typical column base connections. The information obtain in the literature review was then used to create a …

A comparative study : the dynamic behavior of tall buildings with diagrid and hexagrid structural systems subjected to seismic loads
… systems designed to control the governing wind drift requirements were constructed in commercial software ETABS. For each height, one benchmark diagrid structure and two hexagrid structures using horizontal and vertical configurations were modeled. ASCE 7-10 Code based linear dynamic Modal …

Influence of Column-Base Fixity On Lateral Drift of Gable Frames
… for the forces and moments obtained from the wind drift analysis, which assumes pinned connections at the base. The pinned connections provide no moment at the base and have zero rotational stiffness. However, in reality every connection provides some restraint and has some rotational …

Systematics of the Relhaniinae (Asteraceae-Gnaphalieae) in southern Africa : geography and evolution in an endemic Cape plant lineage
… trans-oceanic dispersal facilitated by the West Wind Drift. Important directions for future biogeographic and systematic studies on the Gnaphalieae are identified. One of the Cape clades identified in the above study, the Stoebe clade, is investigated using the same molecular markers and an …

Population structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori)
… waters of South Africa and, following the West Wind Drift, colonised New Zealand and then South America. Secondary radiations resulting in two genetically isolated populations were found for the Kerguelen Island Commerson’s dolphin and the North Island Hector’s dolphin. A comparison of the …
