written by Peter

What Is a Lally Column?

A lally column is a vertical support used to hold up a structure, such as a house or building. It can be used temporarily or permanently to support joists, beams, or other structural elements. Lally columns are typically made of steel and are adjustable in height.

Types of Lally Columns

There are two main types of lally columns: permanent and temporary. Permanent lally columns are used to provide long-term support for a structure, while temporary lally columns are used for short-term support, such as during construction or repairs.

Lally columns are also available in two different styles: adjustable and non-adjustable. Adjustable lally columns are easy to install and can be adjusted to fit the desired height. Non-adjustable lally columns must be cut to the desired height before installation.

When to Use a Lally Column

Lally columns are used in a variety of situations, including:

  • To support a load-bearing wall that has been removed
  • To correct sagging floors
  • To provide temporary support during construction or repairs
  • To support a structure that has been damaged by fire or other events

How to Install a Lally Column

Installing a lally column is a relatively simple process, but it is important to follow the manufacturer’s instructions carefully. Here are the general steps involved:

  1. Measure the distance between the floor and the beam or joist that will be supported by the lally column.
  2. Choose a lally column that is the correct height and weight rating for the job.
  3. Attach the top and bottom plates to the lally column.
  4. Adjust the lally column to the desired height.
  5. Slide the lally column into place and secure it to the floor and the beam or joist.
  6. Check the lally column for plumb and make any necessary adjustments.

Safety Considerations

When installing or working around lally columns, it is important to keep the following safety considerations in mind:

  • Lally columns can become dangerous if they are not installed properly.
  • Lally columns should be perfectly vertical. If a column is even slightly out of plumb, it could fail and cause serious injury or death.
  • Steel plates should be used at the top and bottom of each lally column to prevent the cylindrical ends of the columns from biting into the wood.

How to Maintain Lally Columns

In most cases, permanent lally columns require no maintenance after installation. However, it is important to inspect lally columns regularly for any signs of damage or movement. If you notice any problems, consult with a structural engineer immediately.

Leonardo da Vinci’s Visionary Bridge Design: Tested and Proven After 500 Years

by Rosa
written by Rosa

Leonardo da Vinci’s Visionary Bridge Design: A 500-Year-Old Masterpiece Tested by Modern Engineers

The Enigma of Leonardo’s Bridge Design

In the annals of engineering history, Leonardo da Vinci stands as a towering figure, renowned for his groundbreaking ideas and imaginative designs. Among his many unbuilt creations, one that has particularly captivated the imagination is his proposal for a bridge spanning the Golden Horn in Constantinople.

Leonardo’s design, conceived in response to Sultan Bayezid II’s request for bridge proposals, was unlike anything seen before. It envisioned a single flattened arch, tall enough to allow sailboats to pass beneath, with splayed abutments to stabilize against lateral motion caused by earthquakes.

However, the bridge’s proposed length—a staggering 919 feet—presented a significant obstacle. Conventional building techniques would have required at least ten piers to support the structure, obstructing ship traffic.

MIT Engineers Test the Feasibility of Leonardo’s Design

Five centuries after Leonardo’s initial proposal, engineers at MIT embarked on a project to test the feasibility of his design. Led by John Ochsendorf, the team analyzed Leonardo’s sketches and correspondence, as well as materials available in 1502, to determine the most likely materials and construction methods he would have used.

They concluded that Leonardo would have likely employed stone as the primary building material due to its superior strength and durability. They then constructed a 1/500th scale model of the bridge using 3-D printed parts.

The Critical Role of the Keystone

The keystone, a wedge-shaped stone, played a crucial role in the bridge’s structural stability. When inserted, it locked the other pieces in place through sheer force of compression.

“When we put [the keystone] in, we had to squeeze it,” said engineering student Karly Bast, who worked on the project. “That was the critical moment when we first put the bridge together. I had a lot of doubts.”

Stress Testing and Resilience

To further test the model’s stability, the researchers placed it on movable platforms, creating horizontal motion representative of loose soil or an earthquake. The bridge performed remarkably well, deforming slightly but ultimately resisting collapse.

Insights for Modern Engineering

While Leonardo’s design may not be practical for modern construction due to the availability of stronger and lighter materials, it offers valuable insights for engineers today.

“What we can learn from Leonardo da Vinci’s design is that the form of a structure is very important for its stability,” said Bast. “Not only is Leonardo’s design structurally stable, but the structure is the architecture. It is important to understand this design because it is an example of how engineering and art are not independent from each other.”

The Legacy of Leonardo’s Bridge

Leonardo’s original sketch, lost for centuries, was rediscovered in 1952, providing a glimpse into his creative process. While his bridge design was never built in its entirety, its influence can be seen in modern structures such as Norway’s da Vinci Bridge, which loosely adapts Leonardo’s concept using steel and wood.

The story of Leonardo da Vinci’s bridge design is a testament to the enduring power of human imagination and the enduring relevance of engineering principles. It also highlights the importance of experimentation and collaboration in pushing the boundaries of human innovation.

Nestled deep within the Swiss Alps, the Gotthard Base Tunnel stands as a testament to human ingenuity and engineering prowess. Spanning an astonishing 35.4 miles, it is the world’s longest tunnel, a subterranean masterpiece that has transformed transportation and logistics in Europe.

Historical Context and Inspiration

The majestic Alps have long posed a formidable barrier to rail travel between the North Sea and the Mediterranean. In 1882, the old Gotthard tunnel, a mere 9.3 miles in length, was constructed to overcome this challenge. However, its high elevation of over 3,600 feet made for a slow and arduous journey.

In 1992, Swiss citizens cast their votes in favor of an ambitious plan to construct a tunnel that would go under the mountains. This daring project required the expertise of 2,600 workers who toiled tirelessly in round-the-clock shifts.

Construction and Innovation

The construction of the Gotthard Base Tunnel was a symphony of innovation and technological advancements. Four massive boring machines, each the length of four football fields, relentlessly gnawed their way through the rock. Drill heads equipped with 58 rock-chomping steel “roller cutters” exerted a force of 26 tons, carving a path through the unyielding stone at a rate of approximately 130 feet per day.

The accuracy of the drilling was remarkable. When the north and south tunnels finally met in the middle, after nearly 18 miles of excavation from each direction, they were only off by a few centimeters—a testament to the precision engineering involved.

Environmental Impact and Economic Benefits

The Gotthard Base Tunnel not only enhances transportation but also promotes environmental sustainability. By shifting 40 million tons of freight annually from roads to rails, the tunnel will significantly reduce air pollution. This equates to removing 650,000 trucks from European roads each year.

The economic benefits of the tunnel are also substantial. Swiss Federal Railways trains can now whisk up to 15,000 passengers per day through the tunnels at speeds of 155 miles per hour, slashing travel times between major cities. Additionally, the tunnel’s capacity for 260 cargo trains per day, four times that of the nearest existing tunnel, will facilitate the efficient movement of goods across Europe, from Swiss chocolate to Italian cars.
