Marshall Building

Marshall Building is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Marshall Building rather than just read about it. In short: The Marshall Building, formerly known as the Hoffman & Sons Co. Building, is a historic building in Milwaukee, Wisconsin, United States.

Key takeaways

Marshall Building belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Marshall Building to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Marshall Building from memory before moving on to harder problems.

Reference excerpt

The Marshall Building, formerly known as the Hoffman & Sons Co. Building, is a historic building in Milwaukee, Wisconsin, United States. Part of the Historic Third Ward, the six-story building is the oldest existing example of structural engineer Claude A. P. Turner's Spiral Mushroom System of flat-slab concrete reinforcement.

History The building was originally constructed as a five story structure in 1906 for John Hoffman & Sons Company, a wholesale grocer specializing in the manufacturing of coffee, tea and spices. When the project was in its early stages of design, Milwaukee consulting engineer John Geist came across an article written by Claude A.P. Turner in Engineering News about a new flat-slab system that Turner had developed for the Johnson-Bovey Building in Minneapolis, Minnesota. He traveled to Minneapolis to observe the load tests for the building and asked Turner to design a similar type of flat-slab system for the building in Milwaukee. Turner's flat-slab system differed from previous reinforced concrete construction methods in that it consisted of only floor slabs and supporting columns, eliminating the need for beams below the floors. His Spiral Mushroom System, also known as the Turner System, referred to a cage of radial and tangential bars at the top of each column that imparted shear strength to the slab and also provided cantilever support. A sixth floor was to the structure in 1911 to accommodate the growth in Hoffman's business and was used to accommodate their coffee roasting equipment; however, beginning in the late 1920s the firm began to share space in the building with other manufacturers. The building was purchased in 1947 by developer George Bockl and was renamed the following year after his son Robert Marshall. Bockl sold the building in 1966 but later reacquired it in 1974. On March 8, 1984, the building became a contributing property of the Historic Third Ward District. In 2002, the Marshall Building was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. Today the building is primarily used as office space and art galleries.

Worked examples

Example 1 — a first encounter with Marshall Building

Start with the simplest possible case. Write down what Marshall Building claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Marshall Building before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Marshall Building ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Marshall Building

In research: Marshall Building appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Marshall Building in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Marshall Building is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1906 establishments in Wisconsin, Buildings and structures in Milwaukee, Historic Civil Engineering Landmarks, so understanding it makes those chapters shorter.
In everyday life: Look for Marshall Building outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Marshall Building in simple terms?

The Marshall Building, formerly known as the Hoffman & Sons Co. Building, is a historic building in Milwaukee, Wisconsin, United States.

Why does Marshall Building matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Marshall Building?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
