this is an image of a 12d, spiral shank nail. this nail is designed for easier driving, it twists upon driving creating it’s own fiber connection. with increased withdrawal capacity, this nail is good for using on hard lumber and other dense material. though rarely used in residential construction, this is a good choice for increased withdrawal capacity

Image: structural ridge beam;
a structural member used to support the ends of the rafters at the ridge. structural member used in homes with cathedral ceilings. the ridge beam supports the roof loads and transfers it to posts or gable end wall. in this application, rafter ties are omitted, the beam must be adequately sized to support the roof without sagging.
Inspection & Writing Assignment:
There was evidence of settlement above the bathroom door frame in the west upstairs suite. The wall had settled enough that the door no longer closed without out significant extra effort. Recommend a qualified carpenter, contractor, or structural engineer evaluate and correct as necessary.
Research & Writing Assignment:
I chose to read Attic Pull-Down Ladders, by Nick Gromicko. I commonly see homeowner-installed wood and aluminum pull-down ladders and ladder lengths/connections that have been modified by homeowners. In homes that had original scuttle holes or walk-in attic spaces (that have since been converted to living space), particular attention should be paid to the ceiling structure around the newer pull-down ladder. Evidence of homeowner/non-professional craftsmanship may indicate lack of engineer approval/oversight.
Inspection & Writing Assignment:
The roof structure of this home is comprised of engineered trusses and OSB sheathing. There were no visible signs of damage or any modification to the trusses. The sheathing fasteners were unable to be inspected for adequate size and nailing pattern.

Article: Wind Mitigation
In areas of the country prone to high winds, there are special building practices builders can use to help mitigate possible wind damage. Using impact resistant glass, a secondary water barrier on the roof deck, and hurricane clips/straps on the roof/wall connection are some simple, relatively low-cost options. Builders can also choose to implement a roof design that is less impacted by high winds, i.e. using a hip roof vs. a gable. While there is an initial up front cost to these building alterations, homeowners may receive substantial insurance discounts for implementing them.

In this particular picture, there’s a lot of problem visible, this structure was originally artisanal made with out any engineer calculation, they hire a local contractor to fix the structure but, again with out engineer calculation, we recommend to contact a structural engineer to redo de calculation and new drawing to fix the problem.
Research & Writing Assignment:
This is a Hip Roof, this one was not design by professional engineer, The snow weight was not calculated for the region,and the framing of the roof either, calculation of the vertical load is very important to chose the right material for the conception.
Inspection & Writing Assignment:
The duct vents that run through homes gotta be cleaned and always accessible to clean and most duct vent that are not maintained or neither cleaned can also cause hazard to heat and fire majorly to the dryer lent thats neglected.
Inspection & Writing Assignment:
Wind can produce catastrophic effects on a residential structure. Winds loads can create dynamics forces upon the structure causing both positive and negative pressures upon shear walls and load paths. These downward and upwards pressures push and pull on the structure simultaneously; the resulting wind forces can generate tremendous uplift pressures or suction. The forces caused by wind create significant lateral loads upon shear walls and can cause the structure to lift off its foundation, rack, shift, or slide the structure from its foundation.
Research & Writing Assignment:
I read the article entitled “Structural Design of Lateral Resistance to Wind and Earthquake for the Home Inspector.” The article addresses the design considerations regarding the lateral force resisting systems necessary to restrain and stabilize the structure against wind and seismic events. The design considerations focus mainly on shear wall, diaphragms, and the interconnections between the load bearing systems. The interconnections are most relative the the fastenings of the components and systems. The components that can tie the structure together and transfer the loads upon the path that leads to the structure’s foundation.
Judgment and experience play a critical role in the design of the lateral force resisting systems; moreover, thorough analysis, laboratory testing and real world evaluations play a critical role in new design approaches. In short, the design of the lateral force resisting system is ongoing and testing continues not only in the United States but countries such as England, Australia and Japan. Design of systems that can resist the forces caused by wind and seismic event continues to develop and new design approaches lead to the creation of safer structures.
Inspection & Writing Assignment:
The following photo shows a portion of a home being built with standard balloon framing. The current spin off of modern day balloon framing is called platform framing, where members extend vertically from the floor to the ceiling within each story.
Research & Writing Assignment:
It is important that a homes foundation be designed and built properly to avoid serious potential foundation issues down the line. One major issue is soil expansion. This puts pressure on the foundation, and will cause the foundation to shift. Most serious soul expansion issues should be noticeable to the inspector, usually by large cracks.
Research & Writing Assignment:
-Chimney, is the most common use part of the house in winter fall and winter , it is very important to keep the chimney clean before using it , make sure to have a home inspector to come inspect the chimney it is comon that leakage and collapse may accure when chimney is neglected.

Well, the video said to introduce myself!
I am a building inspector with a local jurisdiction and I thought, with the stay at home order, that I would look into InterNACHI materials for independent study, and to clear the cobwebs.
Here I am.
Hi I am looking forward to learning new things in this class.
Hello. I am a Technical Drafter for Gregory Paul Wallace Structural Engineers. By taking this course, I seek to extend my education to assist identify residential structural design standards at the jobsite. I go with our Inspector in the field inspecting projects, there I verify that my drawings are built correctly. By completing the Residential Structural Design for Home Inspectors Course, I can identify standards at the jobsite beyond the knowledge of my drawings. I will be able to address the topics of residential structural design with our Inspector. I look forward to taking this course.
Introducing myself!
My name is Burris Dixon and I just became an all access member to start my pre-licensing course work for Ohio. I’m very excited to get rolling and learn. Cheers.
