Steel Frame Buildings

שלישי, 21 ביוני, 2011

Boston, Massachusetts, unlike New York or Chicago, is not a city well known for its skyscrapers, which unfortunately means that Boston’s skyscrapers go largely unnoticed by both the casual observer and architectural expert. But if one were to take a little time to note some of Boston’s early taller buildings, they would be pleasantly surprised by both their architecture and their history.

Winthrop Building (1893) This can be considered Boston’s first "skyscraper," if you define your terms according not to height, but according to bearing. A "mere" nine stories, the Winthrop is Boston’s first building not to be bear its load in its walls, but in its skeletal steel framework. In many ways, the Winthrop can be argued to be Boston’s most beautiful and least noticed skyscraper. Gently sloping down from a crowded Lower Washington Street corridor, the Winthrop follows the natural curves of both the natural topography and the streetscape and is, arguably, the most "organic" of the city’s "tall" buildings. The builders didn’t attempt to conquer the landscape but allowed themselves to be guided by the local environment.

Custom House Tower (1915) This tower, when it first appeared on Boston’s skyline, was never considered an architectural gem. But, today, the Custom House is both a very beloved landmark and a living symbol of an historical age. When built, this Federal Government building, at nearly 500 feet, literally towered over Boston whose zoning laws restricted private-sector buildings to a limit of no more than 125 feet. (The Custom House would not be eclipsed until fifty years later, when the Prudential Tower was constructed.) Its landmark clock, with its 10 feet-plus long wooden hands, is arguably one of Boston’s most enduring images of the 20th Century. Today, site lines of the clock tower are protected by Boston’s zoning regulations. Of special note is the tower’s base. It is the previous Custom House. Literally. The granite structure, completed in 1847, became the base for the 20th Century tower. The limestone clad steel tower is literally sitting atop its stone predecessor. Today, the Custom House Tower is a Marriott property.

United Shoe Machinery Building (today "The Landmark") (1930) Once home to the New England shoe conglomerate, this tower is truly one of Boston’s lovelies. In 1928, a change in Boston’s zoning regulations finally allowed for the "skyscraper," and the very first privately constructed tower in Boston was the USMB. A caveat to the height allowance was the "step-back" doctrine. Meaning, the higher a building would aspire, the more removed from the street it must be. So the higher the USMB goes, the more narrow it becomes, ultimately to be capped off by a beautifully tiled pyramid (which is beautifully lit at night). At street level, one finds retail windows and entrances that are gorgeously framed by gilded Art Deco relief. This is Boston’s best representation of the 1920s.

Hancock Building (1947) Located across the street from its better known and younger partner, the Hancock Tower, the Hancock Building is a stately and quietly Art Deco building, which nicely captures the energy and attitudes of those early post WWII years in Boston. Like the United Shoe Machinery Building, there is a stepped pyramid at the top, but atop that there is a weather beacon whose colored lights have been sharing the forecast with Bostonians for over 50 years; Clear blue, clear view / Flashing blue, clouds due / Steady red, rain ahead / Flashing red, snow ahead. (During the summer months, flashing red is used to announce that a Red Sox home game has been officially called due to rain.)

Introduction
This is part 3 of my series, HTML Ebook. In this part of the series we look at the frameset for the HTML ebook project.

Note: If you cannot see the code or if you think anything is missing in this article (broken link, image absent), just contact me at forchatrans@yahoo.com. That is, contact me for the slightest problem you have about what you are reading.

A Frameset
A frameset is still an HTML document, but instead of the HTML BODY element, it has the FRAMESET element. The FRAMESET element defines the different frames for the HTML document. It has the number, position and size of the different frames.

Our Project Frameset
This is the code for the frameset of our project.

There are two framesets, one nested in another. The outer one divides the browser window into two rows: a small row higher for the banner frame and a big row lower for the rest of the window. The nested frameset divides the lower portion of the outer frameset into two columns: the left small column is for the sidebar frame and the right big column (rest of portion) is for the content frame. The outer frameset has the banner frame. The nested frameset has the sidebar frame and the content frame. Note the attributes of the frame tags.

Scrolling
The banner frame does not have scroll bars, so it has the value, "no" for the attribute, "scrolling". The sidebar frame has scroll bars, so it has the value, "yes" for the attribute, "scrolling". The content frame has scroll bars, so it has the value, "yes" for the attribute, "scrolling". The information (text and maybe some images) in the content frame can always grow downward below the bottom edge of the content frame; so the content frame needs scroll bars. As the tree of links in the sidebar is expanded, it grows to the right and downward, and may cross the right and bottom sidebar edges, so the sidebar needs scroll bars.

Frame Borders
By default a frame would display its borders. So the above frameset would display borders for the frames. Let us allow this situation for this simple project. In your commercial project, you can remove the borders, and give the pages for the different frames, slightly different background colors, to differentiate the frames; you can also add some beauty.

The Source Attributes
This frameset page, the banner, sidebar and initial content HTML page are in the same directory (head directory). So the values of the source attributes for the frames are not preceded by any path. Note the names of these values, which are the names for the HTML files for the frames. The files for the banner and sidebar will never change. The file for the content will change as the user clicks links.

Name Attribute of Content Frame
The name attribute of any frame gives the name of that frame. This value of the name attribute of the content frame is, "content". This value will be used to send an HTML page to the content frame.

JavaScript
The frameset has a JavaScript. This JavaScript is in the HEAD element of the frameset. The JavaScript has just the declaration of a variable. We shall come back to this variable later.

Wow, not as difficult as it appeared. We take a break here and continue in the next part of the series.
