bolts evenly spaced around a bolt circle 12 in. in diameter, and six 4 -in. aluminum bolts on a concentric bolt circle 8 in. in diameter. What torque can be applied without exceeding 15000 psi in the steel or 10000 psi in the aluminum? Assume Gst = 12 x 106 psi and Gal = 4 x 106 psi.

Calculate the maximum tensile load, Ta or Tu of the connection shown in Figure 7. Theconnection consists of two 3/8" plates fastened to each side of one 13/16" plate.Assume 7/8" diameter bolts and standard punched holes. Use A36 steel. The plate is 13” wide. Note: Be sure to check all failure modes; bolt failure modes, and member failure modes(including block shear)

Please answer hand writing

1. Assumptions and Specifications:- **Material for Frames:** A36 or A992 steel- **Material for Plates:** A36 steel- **Material for Bolts:** ASTM A325 (High-strength bolts)- **Material for Welds:** E70xx (Welding electrodes)- **Spans:** - **X Direction:** 6 meters - **Y Direction:** 7 meters- **Column Length:** 3.5 meters (half of the longest span)- **Floor Slab:** Reinforced concrete slab (assumed for typical design) ### 2. Design Calculations: #### **a. Design of Interior Column:** - **Column Size:** Assume a typical size (e.g., W250x250x12.5, or equivalent) based on load calculations.- **Load Calculation:** - **Dead Load (DL):** Floor slab self-weight and additional permanent loads. - **Live Load (LL):** Assume a typical load (e.g., 5 kN/m² for office spaces). - **Total Load per Column:** Combine dead and live loads. - **Manual Calculations:** - **Axial Load Analysis:** Calculate the axial load on the column from the floor slab and beam loads. - **Column Design:** Verify the column…

The allowable load for a high-strength bolted connection is determined by considering shear, bearing and tension separately.  Yes  No

2) Why Long rows of bolts ,perpendicular to grain fastened to a single cover plate, should be avoided? (support your answer with an illustration) 3) What are the consideration (in design) for the end of beams (including the deflection effect) ? (support your answer with an illustration) 4) What is timber seasoning? what are the advantages of timber seasoning 5) what is carriage bolt and its usage?
