I currently have an older bridge in my backyard spanning a…

Thank you for using justanswer and please let me know if you need anything else.

The I-beam size needed will be larger than the W10x49 that I initially advised, assuming an 1800-lb static load from the bridge decking and a 5000-lb dynamic load for a moving load like a riding lawnmower behind a small utility trailer.

A structural engineer will need to take additional considerations like the span length, the support conditions, the loading configuration, and any applicable building laws or regulations into account to determine the needed size and kind of I-beam for your circumstance.

However, based on these loads, a W12x53 (12-inch deep, 53 pounds per foot) steel I-beam could be suitable for your situation.

This size of the I-beam should be able to support the specified static and dynamic loads, as well as the weight of the bridge decking.

The short-term disability insurance program in New Jersey offers temporary pay replacement benefits to qualified workers who are unable to work because of an illness or accident that is not connected to their line of employment.

The New Jersey Department of Labor and Workforce Development is in charge of running the program.

In order to be eligible for short-term disability benefits in New Jersey, you must fulfill a number of requirements, such as having earned enough money and being diagnosed with a medical condition that disqualifies you from working.

Unless your dental problem is so serious that it stops you from working and is backed by medical paperwork, traveling to Colombia for dental implants is not likely to qualify you for short-term disability benefits.

So sorry about that.

True, the load capacity of the i-beams is normally calculated with a safety factor. A margin of safety, also known as a buffer, is built into the calculations to allow for varying loads, material strengths, and other variables that might have an impact on the performance of the bridge.

The unique design and the requirements of the relevant building standards and regulations will determine the exact factor of safety that is applied. Yet, depending on the situation, average safety factors for bridge design might range from 1.5 to 2.0 or higher.

A factor of safety of 1.5 would indicate that the real load capacity of the i-beams is 15,000 pounds, while a factor of safety of 2.0 would indicate that the actual load capacity is 20,000 pounds, for instance, if the estimated load capacity of the i-beams is 10,000 pounds.

In order to make sure that the bridge is both safe and structurally sound, the engineer will take into account the unique safety requirements that are necessary for your design.
