Thinking Outside The Box: New Approaches To Very Large Flexible Diaphragms, John W. Lawson
Thinking Outside The Box: New Approaches To Very Large Flexible Diaphragms, John W. Lawson
Architectural Engineering
This paper discusses the past design practices of flexible diaphragms, the current trend to very large diaphragms, and the new tools available to properly evaluate and engineer these large roof systems. Higher shear demands are accommodated by higher plywood/OSB and steel deck shear capacities accepted by the IBe. A new collective chord technique is presented to more accurately reflect large diaphragm behavior. In addition, these very large diaphragms have significant lateral deflection issues that can now be evaluated in the IBC. The new AF&PA deflection equations for wood diaphragms are presented as well as a technique to compute deflections of …
Deflection Limits For Tilt-Up Wall Serviceability - The History Behind Changes To Chapter 14 Of Aci 318, John Lawson
Deflection Limits For Tilt-Up Wall Serviceability - The History Behind Changes To Chapter 14 Of Aci 318, John Lawson
Architectural Engineering
Tilt-up construction is one of the most ubiquitous forms of commercial construction in many parts of the country. Thanks to its efficient wall and roof systems, more than 700 million ft2 (65 million m2) of tilt-up buildings were constructed in the U.S. in 2006.1
Tilt-up's current popularity is even more remarkable considering that it wasn't until the 1980s that building codes began to recognize the unique design of slender tilt-up wall panels. In fact, it wasn't until ACI 318-992 was published that the design of slender wall panels was codified on a national level. Of …
Evaluating Structural Form: Is It Sculpture, Architecture Or Structure?, Edmond P. Saliklis
Evaluating Structural Form: Is It Sculpture, Architecture Or Structure?, Edmond P. Saliklis
Architectural Engineering
The purpose of this paper is to discuss the idea of a continuum between sculpture form, architectural form and structural form. A linkage between the various forms will be proposed, and several scholarly views on this subject will be presented. Then, this paper will describe a brief web-based survey which tested people’s subjective categorization of various sculptural, architectural and structural forms. The target audience of the web-based survey was college students interested in building design and high school students. Finally, this paper will analyze whether or not presenting the respondents with the idea of a proposed continuum between such forms …
Tedesko’S Philadelphia Skating Club: Refinement Of An Idea, Edmond P. Saliklis, David P. Billington, Anneliza W. Carmalt
Tedesko’S Philadelphia Skating Club: Refinement Of An Idea, Edmond P. Saliklis, David P. Billington, Anneliza W. Carmalt
Architectural Engineering
This paper presents new aspects of Anton Tedesko’s design for an important thin shell concrete roof. The study of this roof results from the examination of original engineering drawings and calculations which we present with the goal of promoting a greater understanding of the structural design of a major figure in the tradition of 20th century building.
