Design Considerations For The Construction And Operation Of Flour Milling Facilities. Part I: Planning, Structural, And Life Safety Considerations, Gregory D. Williams, Kurt A. Rosentrater
Design Considerations For The Construction And Operation Of Flour Milling Facilities. Part I: Planning, Structural, And Life Safety Considerations, Gregory D. Williams, Kurt A. Rosentrater

Flour milling facilities have been the cornerstone of agricultural processing for centuries. Like most agri-industrial production facilities, flour milling facilities have a number of unique design requirements. Design information, to date, has been limited. In an effort to summarize state of the art design procedures for flour milling facilities constructed in the United States, an overview of accepted standards and procedures has been assembled and discussed. With this paper engineers should become more familiar with specific design considerations for flour milling production facilities and develop appropriate references to expand their knowledge base. Educators may find this paper useful too.

Insufficient concrete cover, poor design or workmanship, and presence of large amounts of aggressive agents including environmental factors all can lead to cracking of the concrete and corrosion of the steel rebar. The problems of steel corrosion are avoided with the use of FRPs because FRP materials are nonmetallic and noncorrosive. In addition, FRP materials exhibit several properties including high tensile strength, that make them suitable for the use as structural reinforcement. Furthermore, codes and design guide provisions have been recently prepared for the use of FRP bars in concrete structures for bridges and buildings.

Welded steel Moment-Resisting Frames (MRFs) were long considered as one the most earthquake-resistant types of structures. Recently, the idea of applying the post-tensioning technology to achieve moment resistant structural systems has been investigated at the University of California, San Diego. Since 1996, moment-resisting connections using post-tensioning concepts have been developed and tested for precast concrete beam-to-column connections, and concrete shear walls.

A permit truck which exceeds the predefined limit of 108 kips is defined as a superload in Indiana. This study was conducted to examine the long-term effects of superload trucks on the performance of typical slab-on-girder bridges and to assess the likelihood of causing immediate damage. Typical steel and prestressed concrete slab-on-girder type bridges were analyzed using both beam line analysis and detailed finite element models. Furthermore, one prestressed concrete bridge and one steel bridge were instrumented using more than 50 sensors each. Strains and deflections were measured during a live load test, and each bridge was monitored for more …

The literature review of prior heat straightening research indicated that significant research has been conducted on the development of: (i) heat straightening repair techniques and their field implementation, (ii) guidelines and recommendations for heat straightening repair, (iii) empirical procedures for estimating plastic rotations achieved during heat straightening, (iv) empirical procedures for predicting residual stresses caused by heat straightening, and (v) the effects of heat straightening on the structural properties of repaired bridges. Currently, there is a need for additional research on: (a) the fatigue performance of heat straightened beams, (ii) the effects of single and multiple heat straightening on the …
