Wondering if anyone has experience with code compliance with paver/pedestal systems. I am building 9psf pavers on a pedestal system at about grade level. These systems are becoming more common but would never meet wind uplift code requirements (Calculated to be 26psf on a 120mph wind). My...

Hello, Does anyone know of a good resource to investigate the loads imposed by parapet clamps (C hooks) on parapet walls? Thanks

If a concrete slab does not meet the required air-entrainment, can the slab be rejected entiriely? In this case, the testor failed to reject the concrete at the time of the pour even though he identified the issue at the time of the pour. He is now asking that the entire slab be removed and...

What effect would raising a parapet wall height have on snow drifts on the "existing" roof structure? A one story store is raising the parapet (from 4' to 6') with light gage framing and a kicker at a 45 degree angle which I guess sheds the load immediately adjacent to the parapet. I was...

I am looking to provide short concrete (or block) columns in a crawl space to support a wooden beam (supporting first floor above). There has been some settlement of the existing block columns which I assume is due to a poor underlying soil condition. My thought is to construct a 12"...

I am in the process of restoring a concrete parking garage topped with asphalt designed for 2000# concetrated loads (not alot considering weights of asphalt spreaders, rollers and bobcats with filled buckets) I understand I can allow higher loads during construction (restoration) since they are...

I am involved in a project where we are restoring concrete spandrels or as I hear them refered to as "eyebrows." Each floor line of a multistory building the concrete has deteriorated (water intrusion leading to rebar corrosion and concrete spalling). The question is, in making these repairs...

I am building a pergola off a house. 2 main 2"x 12" beams run perpendicular to the house wall (17' apart) and are properly secured (fixed) to the wall on one end and to a 6x6 post (for each) on the other. These main beams are 17' long and 2x8 beams run accross them at 12"o.c. parrallel to the...

I am reviewing a 3 story wood building (platform framing) with 6' foot window headers. My reactions at the end of these headers are R3 (at the top) = 348#, R2 = 3520# (including the 348 above) and R1 (1st floor window) = 6692# (which includes the 3520 above). R3 is low because it is only...

Can someone provide information regarding references on analyzing moisture decay on wood sill plates? That is, I am evaluating decay on a wood sill plate and the "threshold" on when the sill plate should be replaced. Thank you.

Can anyone direct me to design aids for wood retaining walls? Charts/software etc.? I am designing an 8' high wall with no-slope or surcharge behind. I will replace clay soils behind with drainable bankrun or the like... Thank you ...

I am investigating a 1-story structure that has 3 bays with (3) W12x22 beams runing 250" long 6'O.C.. 12" thick concrete is located BETWEEN the beams. When I analyze the steel, it is insufficient to support the concrete as a dead load + live loads and I believe that the concrete is actually...

I am evaluating a 7' high retaining wall constructed of 6"x6" lumber with deadmen stagered at every 8' O.C.. I've never evaluated this kind of wall and am having a hard time finding engineering principles/design data. Does anyone have any information or links they can share? Thank you very...

I am evaluating cracks in a 100 foot tall brick structure. The brick encases a steel structure. 30 foot long vertical cracks THROUGH the brick work are apparent at two of the corners (approx 3' from the corner). I am looking for masonry engineering references particularly related to older...

How does one go about analyzing an old concrete beam without knowing what size/amt of rebar was used? (No drawings are available). I am a civil engineer with some structural background. Do I simply assume minimum steel reinforcing ratio was used for the particular cross-sectional area of the...

I am investigating whether a wood roof structure can support an outrigger scaffold setup. The weight on the steel scaffold is approximately 1300# (Mostly on the Back) to counterweight the platform that hangs over the building. This results in 600# point loads on the 2 rear scaffold legs...

Hello all, Does anyone know of any seminars on structures. I have a Masters degree in civil engineering but would like to strengthen my knowledge in structural engineering. I believe an association seminar would be more practical than a university class. Thanks all... I live in NY but am...

I'm wondering if anybody can help me with this question... EXISTING CONDITION - TOP PLATES OF BASEMENT COLUMNS FULLY SUPPORT BUILT-UP-BEAM (3-2x10'S) PROPOSED CONDITION - ADD 3/4" X 9" PLATE AT EACH SIDE OF BUILT-UP-BEAM TO CREATE FLITCH PLATE (in order to remove a middle column) PROBLEM? -...

I need to evaluate an existing steel truss system in order to see if it can support an additional 5 psf roof load. There would be great difficulty in measuring the existing truss as it is a commercial building located high off the ground. Is it acceptable to approach this by measuring existing...

I saw in a Journal of Light Construction an article that stated the following loads applied on basement walls. 8' wall height Backfill wght of soil = 30 pcf/ft (Class I soil) Pressure calculated = 1250#/ft 8' height with wght of soil = 60 pcf/ft P=2500#/ft 10' hieght with wght of soil...
