Lower Cost Lightweight Cold-Formed Portal Frames, B. W. J. Van Rensburg, G. P. De Vos
Lower Cost Lightweight Cold-Formed Portal Frames, B. W. J. Van Rensburg, G. P. De Vos
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
Southern Africa has a dire need for housing small industries and people, and concomitantly the creation of employment. It is common to use hot-rolled steel sections for industrial structures, which are pre-manufactured and then bolted together on site. In this paper an alternative structural concept for low-rise portals for light industries is proposed, whereby the total frame is made up of standard cold-formed sections which are cut and welded together on site. The cladding material is employed as an integral structural component through the principles of stressed skin diaphragm action. A short pile footing is proposed to provide a degree …

The Lateral Torsional Buckling Strength Of Cold-Formed Stainless Steel Beams, G. J. Van Den Berg, P. J. Bredenkamp
The Lateral Torsional Buckling Strength Of Cold-Formed Stainless Steel Beams, G. J. Van Den Berg, P. J. Bredenkamp
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The findings of an investigation of the lateral torsional buckling strength of cold-formed stainless steel beams are reported in this study. The sections under consideration are cold-formed lipped channel sections spot-welded back to back to form doubly-symmetric lipped I-beams. The beams were fabricated from a modified AISI Type 409 stainless steel, designated Type 3CR12 corrosion resisting steel. The purpose of this study is to compare the experimental lateral torsional buckling strengths of doubly-symmetric beams to the theoretical predictions proposed by the ASCE Specification for the Design of Cold-Formed Stainless Steel Structural Members. It was concluded in this investigation that an …

The Strength Of Partially Stiffened Stainless Steel Compression Members, Y. Buitendag, G. J. Van Den Berg
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The instability of partially stiffened stainless steel compression members due to local buckling of the flange element or flange and lip interaction has not been studied before. In this investigation the critical local buckling and post-buckling behaviour of cold-formed partially stiffened stainless steel compression elements is studied. It is concluded in this investigation that a plasticity reduction factor should be used to evaluate the critical local buckling stress as well as the effective width to calculate the ultimate capacity of partially stiffened stainless steel compression members.

Web Crippling Of Stainless Steel Cold-Formed Beams, S. A. Korvink, G. J. Van Den Berg
CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)
The results of an investigation on the web crippling strength of cold-formed stainless steel channel sections are presented in this paper. The steels under consideration are AlSI Type 430 stainless steel and a modified AlSI Type 409, designated Type 3CR12 corrosion resisting steel. The lipped channel sections were manufactured by a press braking process. Beams were tested in pairs, lips facing, in an interior-one-flange loading configuration. Experimental results were compared with the theoretical predictions given in the 1991 edition of the Specification for the Design of Cold-Formed Stainless Steel Structural Members. It was concluded in this study that the experimental …

Geotechnical Problems Encountered During The Excavation Of Underground Cavities For Varahi Hydro Electric Project, H. V. Eswaraiah, V. S. Upadhyaya, B. N. Vishwanath
International Conference on Case Histories in Geotechnical Engineering
Varahi river in Karnataka State, India originates on the Western Ghats and is harnessed for power generation by constructing three dams. The water is conveyed through two inclined pressure shaft to the underground power house below the Ghats. The underground power house of the Varahi Hydro Electric Project executed by the Karnataka Power Corporation has 2 units of 135 MW each in the first stage with a provision to add two more identical units. Three underground cavities are excavated parallel to one another for housing the rotary valves, generators and the transformers respectively and are at a gee-static head of …

Stabilization Of A Tailings Dam By De-Watering, A. B. Fourie, G. I. Mcphail
Stabilization Of A Tailings Dam By De-Watering, A. B. Fourie, G. I. Mcphail
International Conference on Case Histories in Geotechnical Engineering
The failure of the outer slope of one of the paddocks of a tailings dam, resulted in a significant decrease in the area available for tailings deposition. Overloading of the remaining five paddocks resulted. To maintain the stability of the existing dam whilst construction of new disposal facilities was in progress, three techniques were investigated; horizontal, push-in drains at the dam toe, a rock buttress around the operational paddocks, and vertical de-watering wells installed on the first terrace, or ‘step-back’ of the dam. De-watering wells proved most effective, and 165 wells were installed. A monitoring programme included regular determination of …
Geomechanical Studies For A Himalayan Tunnel In Jointed Dolomites: A Case History, G. S. Saini, A. K. Dube
Geomechanical Studies For A Himalayan Tunnel In Jointed Dolomites: A Case History, G. S. Saini, A. K. Dube
International Conference on Case Histories in Geotechnical Engineering
Reported case history of Himalayan tunnel reveals that Barton's and Bieniawski's classification systems provide better assessment of the rock mass behavior. The design and shear strength parameters derived from these classifications provided a preliminary design of the tunnel, which has been critically evaluated with the design, adopted at site. Based on the structural feature and ground water conditions, a number of tunnelling conditions have been predicted. The studies indicated the loosening rock pressures would be occuring at site with an estimated range of 0. 25 kg/cm2 to 3. 58 kg/cm2. Problems of roof collapse, flowing ground condition …
The Impact Of Rising Ground Water Level On The Geotechnical Behavior Of Soil In Hot Climate Regions, A. S. Stipho
The Impact Of Rising Ground Water Level On The Geotechnical Behavior Of Soil In Hot Climate Regions, A. S. Stipho
International Conference on Case Histories in Geotechnical Engineering
The continuous development and industrial changes in Saudi Arabia necessitates large ground water exploitation and brought about significant changes to the ground water regime. The alarming evidence of rising shallow ground water level and the widespread structural problems have mitigate the extra demand to develop special geotechnical awareness, standard testing and designing procedures to minimize the impact of wetting on soil behavior in the hot climate region. Field and laboratory test results on typical soil samples have established the influence of rising moisture and exemplified the adverse levels of collapse manifested by the large reduction in shearing strength and the …
