Hi I have a 7 year old house all 16" tgi joists 2' on center with 2 layers of 3/4 t/g plywood over them. It was supposedly build extra heavy for tile.

The great room is 24x24 with the tji's spanning the whole floor at about 23'In the past year it has become bouncy, noticed mostly when the two dogs run across it. But the lamp shades move and it's freaking me out.

It's a full unfinished basement underneath. There is no x or other bracing on the TGI's. I measured the center of the floor and it's about 1 1/2" lower than the edges.

Is there anyway to stengthen the floor or raise it back up? Can more joists be installed with the wiring already going through them? I may be able to support it about 1/3 of the way in with a wall when the basement is finished. Should some type of bracing be installed on the joists?

Please let me know so I can find a contractor to help.

Thanks for any help.

The engineers over at the JohnBridge tile forum have access to the TGI span tables and are willing to share........

Register and post your floor/truss/span/dimensions......They'll be able to tell if the floor IS stiff enough for tile.......

Yes .......the wall downstairs is one way to stiffen the floor by shortening the effective span.......

Do any of the joists appear to leaning to the side or are they still striaght up and down?

Are the dimensions between them the same at the top and bottom?

Поступил вопрос:
Хочу развеселить друга прикольным но приемлимым по цене
Не могу ничего придумать что подарить. Тут наверняка есть, кто подскажет.
Подскажите плиз!

Также была такая проблема.
Сейчас могу посоветовать вот это:
Самое простое решение - подарить прикольную и милую футболку.
Что называется - дешево и сердито. Нерасходно но очень запоминается. Показываю картинку. Есть много других вариантов.
