Local Buckling Of Cold-Formed Steel Structural Members Having Initially Curved Compression Elements, William M. Mckinney Jan 1974

Local Buckling Of Cold-Formed Steel Structural Members Having Initially Curved Compression Elements, William M. Mckinney

Masters Theses

"A comprehensive investigation of the effect of initial deviation from flatness on buckling stress and post-buckling strength of compression elements in structural plate members is presented. The study of stiffened and unstiffened elements expands the scope of elastic stability for initially curved plates. Finite element techniques were utilized for the study of unstiffened elements"--Abstract, page ii.


A Planning Study On The Electrical Load Requirement For The New Town Of Pattonsburg, Javad Yousefian Jan 1974

A Planning Study On The Electrical Load Requirement For The New Town Of Pattonsburg, Javad Yousefian

Masters Theses

"Because of an Army Corps of Engineer proposed new dam on the Grand River 1 the original town of Pattonsburg, Missouri was to be inundated by the resulting lake reservoir formed above the dam. The city planners proposed the relocation of the town site adjacent to the new lake, forming a lake side community attractive to both a residential population and for industrial locations.

The electrical power loads of New Pattonsburg's residential, industrial, commercial, and municipal areas, as well as its street lighting power requirements, were planned for a population of 50,000. Statistical analysis of demographic surveys was employed to …


Distribution Of Ambient Particulates And Particulate Trace Metals Around The Amax Smelter, Pramod Maneklal Shah Jan 1974

Distribution Of Ambient Particulates And Particulate Trace Metals Around The Amax Smelter, Pramod Maneklal Shah

Masters Theses

"The purpose of this investigation was to study the distribution of metallic particulates in the air surrounding the AMAX Lead Company of Missouri smelter in the "New Lead Belt" of southeast Missouri. The study included the evaluation of the temporal and spatial variation of dustfall and deposition rates of settleable particulate lead, zinc, copper, and cadmium, and transport and distribution of total suspended particulates and suspended particulate trace metals.

The study was conducted within a 3 x 3-mile grid around the smelter employing twenty dustfall stations and five HiVolurne samplers. The samples collected were analyzed for lead, zinc, copper and …


Laboratory Evaluation Of Dynamic Soil Properties By Ultrasonic Testing Methods, Ronald Maurice Eckelkamp Jan 1974

Laboratory Evaluation Of Dynamic Soil Properties By Ultrasonic Testing Methods, Ronald Maurice Eckelkamp

Masters Theses

"Measurement of ultrasonic compression and shear wave velocities through a soil material has been made with a pulse wave generator developed at the University of Missouri-Rolla. The variation of these velocities along with the behavior of the dynamic material parameters of the material (Young's modulus, shear modulus, Poisson's ratio) with void ratio and degree of saturation were determined. Compression wave velocity, shear wave velocity, Young's modulus and shear modulus were found to decrease with increasing void ratio; degree of saturation was of little influence. Wave attenuation could not be measured by the test procedure used"--Abstract, page ii.


Evaluation Of Methods For The Recovery, Chemical And Toxicological Characterization Of Trace Organics, James Robert Matthews Jan 1974

Evaluation Of Methods For The Recovery, Chemical And Toxicological Characterization Of Trace Organics, James Robert Matthews

Doctoral Dissertations

"Organic contaminants are generated in substantial quantities by the activities of man and through natural processes, and are present in natural runoff, industrial wastes, and agricultural discharges; synthetic organic chemicals, many of which are refractory and reach surface and subsurface water, are of particular significance. Earlier studies have generally emphasized the organoleptic and esthetic problems caused by trace organics, although their acute and long-term toxic potential has also been recognized.

The overall objective of this investigation was the analytical and toxicological characterization of trace organics recovered concomitantly from Missouri waters of varied character by large-scale solvent extraction (SEM) and carbon …


Removal Of Nutrients By Sorption On Activated Alumina, Checkman Michael Yue Jan 1974

Removal Of Nutrients By Sorption On Activated Alumina, Checkman Michael Yue

Doctoral Dissertations

"The nutrient enrichment of surface, primarily impounded, water and the associated problems of accelerated eutrophication and prolific algal growth have become a nationwide concern. Phosphorus and nitrogen are considered to be the key elements in abating eutrophication and are contributed from many sources, natural and manmade; prominent among these is the discharge of domestic and industrial wastes.

The purpose of this study was to evaluate the removal of nutrients, primarily phosphorus and nitrogen, with activated alumina using a continuous-flow pilot plant system. Specific objectives were the: development and construction of appropriate bench and field-scale pilot plant units utilizing the rapid …

Recommended Procedures For Conducting Pull-Over, Pull-Out And Single-Shear Tests Of Mechanical Connections, John Fraczek, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

1. SCOPE 1.1 These methods cover procedures and definitions for the mechanical testing of joints formed by connecting a cold-formed steel member to a cold-formed or hot-rolled steel member with one or more mechanical fasteners. The purpose of these procedures is the determination of the load capacities of the joints so formed. 1.2 The term "mechanical fastener" or "fastener" shall be defined as any mechanical device used in the connection of two or more members, inclusive of such devices as bolts, tapping screws and rivets but exclusive of welds and adhesives. 1.3 The following mechanical tests are described: Sections Pull-Over …

Local And Overall Buckling Of Cold-Formed Compression Members, John T. Dewolf, George Winter, Teoman Peköz Nov 1973

Local And Overall Buckling Of Cold-Formed Compression Members, John T. Dewolf, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

The objective of this investigation has been to develop information on the interaction between local plate buckling and overall column buckling in cold-formed compression members with a view toward possible improvement of those provisions in the American Iron and Steel Institute Specification for the Design or Cold-Formed Steel Structural Members concerned with column design. Two types of compression members were tested: two channels connected flange-to-flange to form a box section, and two channels connected back-to-back to form an I-section. For both of these shapes, the stress at which local buckling occurs and the postbuckling strength were varied by varying the …
