jjl317 (Civil/Environmental) There are many situations that I need to use LVLs. - Cantilevered joists or beam for balcony - Reinforcing existing joists or beam with a limited depth due to existing condition - If a beam supports 4' cantilever for balcony and 8' spanning into the interior, only...

jayrod12 (Structural) Thank you for the recommendation. Did 'Encapsulate the beam' mean wrapping Tyvek around entire beam, covering the beam, or something else?

Dear Engineering folks, LVL is NOT suitable for the exterior application according to the manufacturer, Weyerhaeuser. Beams of a 1covered porch that have a covering and waterproofing roof, which is very limited chance of exposing to the weather, can use LVL? Or, this application is still...

Existing house has top plates at 8'-0" high, but the owner wants to raise to 13'-0". I'm thinking of two ways of extending the studs. First way is to install 5'-0" new studs on top of existing top plates and Simpson straps on both sides of studs from new studs to old studs passing top plates...

In many cases of constructions, I've seen contractors brought sandbags rather than compacted fill. At sloped grade, the heights of boundary grade beams vary and sometimes its height can be 4-5 feet. Do these grade beams not require design as 'retaining wall'?

Contrator's point is that NO dowels are needed when NO construction joints are created with monolithic pour. Agree?

Contractor brings sand bags under the slab on grade. I don't know how they compact sand bags. They usually stack them up to the bottom of slab on grade and install membrane and rebars, and then pour concrete.

Most time, I used L-shaped slab-to-grade beam dowel bars, but a contractor prefers pouring monolithic concrete with no dowels. Pros and cons?

boo1 Playswow Wahoo docks has very good presentation of anchoring systems and other information. Thank you so much for your help!

BUGGAR Fortunately, these structures will be floating on river, not ocean. I may not think of wave action, but water load (AASHTO) seems big enough to consider very carefully. Thanks for your input. shepherd The site is not at ocean, but river. However, any information can be helpful to me, so...

medeek The site is not at ocean, there's no wave action. However, flash flood makes big impact on the design I believe. Thanks for your input. cessna98j Thank you so much for the link and information. I'm still reading the web link and AASHTO, and they shall be very helpful to my design. 100yr...

KootK Thank you for the link and the reference book. SlideRuleEra Thank you for the photo and advice. My dock and house are a lot different than the photo. I was thinking of using pile system with pile rollers, so the structures are allowed to move up and down according to water elevation...

I have researched many web sites, design examples and code books, but really couldn't find any applicable and helpful references for designing a boat dock and boat house. These structures will float on the water and move up and down depending on the water level, so flood load really doesn't...

Many thanks to all of you. I was surprised with Vulcraft's charge for providing information of their product. My service charge to check the capacity is not expensive, possibly cheaper than Vulcraft's charge, so my client may not want to spend money to get the information of Vulcraft's steel...

I'm working on a project of installing a new heavy equipment on the existing roof structure. Roof structure is made of metal deck with insulation and open steel joists are supporting the deck. Site visit found the existing steel joist is like this in the photo. It reads 3371138-1J24, VULCRAFT...

dhengr If I get an answer from other engineers, I intended to multiply to apply to my situation. Code requires using uniform live load and my approach to beg opinion was not that bad in terms of code-compliance approach. You may read the notes below and if you want to share your opinion, that'll...

TehMightyEngineer The cabinet height is tall, so it's heavy. I will set 25 cabinets next to each other, so it can cause over-loading problem, don't you think? MoterCity, manstrom Let's assume four football players weighing average 310lbs are invited to a friend's house. They were sitting in a...

Here's a silly question. A structural slab is designed for 50 psf of Live Load. I want to bring a steel cabinet with 40 psf of empty weight. Can I fill the cabinet only for weighing 10 psf more?

JAE and Ron --- Thank you for sharing your idea. Yes, that's right. It's just sidewalk, but the square footage is not small. The scaling and mortar flaking problem are limited in small sections now, but the rest of huge areas have started showing flaking problem. I'm pretty sure those areas will...
