- Description
- The Corpus Christi Army Depot has a requirement to upgrade a three-ton crane to a five-ton. FOB destination Corpus Christi Army Depot, TX. Some of the requirements are listed below. You can email cevans@ccad.army.mil for a complete copy of the RFQ . A site visit will be scheduled approximately 14 days from the date of issue of the RFQ. 3. Inspection of Hangars Four types of trusses were identified as shown in Figures 2.1 and 2.2. Every member was labeled for each type and can be located by defining the hangar number, truss type number, truss location on plan drawing, section of the truss, and a unique label. The most severe problems in the hangars were in the door pockets . Three typical problems were identified in the door pockets: (1) the base beam of some columns were severely corroded, (2) the flange and webs of some columns at the top of concrete walls were also severely corroded, and (3) diagonal braces were either bent or loose. Recommendations for repair to return damaged members to their original condition, when necessary will be provided in Chapter 7 following the completion of the structural analysis i n Chapter 5. Deficiencies Reported During Inspection of Hangar 43 The following notes are reported from observations during inspection. These notes are associated with strength reduction and in many cases repair is required. For location of members on plan view of the hangars see Figure 2.3. For member locations on the e levation views see Figures 2.4 and 2.5. Notes 1 through 3 are for buckled members. 1. T1-J 7/V (Double angle 6 x 3? x 5/16 x 180 in.) " Bent vertical member, one angle of the double angle section 2. T2-N 7/V (Double angle 6 x 3? x 5/16 x 180 in.) " Bent vertical member. 3. T2-A S21 (Double angle 3? x 2? x 5/16 x 360.5 in.) " Bent double angle diagonal bracing members. Notes 4 through 8 are for corroded members with reduced strength. Corrosion was classified as minor or major depending on the extent of corrosion observed in the member. More frequent painting is recommended to protect structural members from further corrosions. Minor corrosion is estimated to reduce the strength of the member by 5 percent whereas major corrosion is estimated to result in 10 percent reduction in strength of members. Note 9 pertains to estimated strength reduction due to attachments loads by both welds and bolts connection to the columns. The members were not damaged, but a 5 percent strength reduction was considered. 4. All steel members in the hangars open area " Minor corrosion " 5 percent strength reduction. 5. Column N-S ? (8-H-31, length: 426 in.) " Major corrosion at the columns base " 10 percent strength reduction. 6. Column P-S ? (12-1-25, length: 426 in.) " Major corrosion at the columns base " 10 percent strength reduction. 7. Column A-5 (8-H-31, length: 426 in.) " Minor corrosion at the columns base " 5 percent strength reduction. 8. Column AA-4 ? (12-I-25, length: 426 in.) " Minor corrosion of the column at the height of the concrete wall, approximately 5 ft above the floor " 5 percent strength reduction. 9. There are many attachments by both welds and bolts connection to the columns of lines 2 and 4. " Members do not look damaged " A 5 percent strength reduction was considered. Repair of Deficient Members Observed During Inspection This chapter outlines immediate action needed based on observations during inspection, to return damaged members to their original condition. Proposed repair for all deficient members is presented here with illustrative drawings. General notes for proposed repair techniques are shown in General Retrofit Notes. Repair in Hangar 43 Notes 1 through 3 are for the buckled members presented in Chapter 2. For Note 1, repair as shown in Figure D-2. For Notes 2 and 3, it is recommended to replace the damaged existing members with identical or slightly stronger members. The new members shall have the same connection details as the existing members with the same sizes and configurations of bolts and welds (if they exist). 1. T1-J 7/V (Double angle 6 x 3? x 5/16 x 180 in.) " Bent vertical member, one angle of the double angle section " Repair as shown in Figure D-2 " Capacity-demand ratio is less than 0.5. 2. T2-N 7/V (Double angle 6 x 3? x 5/16 x 180 in.) " Bent vertical member " Capacity-demand ratio is less than 0.5. 3. T2-A S21 (Double angle 3? x 2? x 5/16 x 360.5 in.) " Bent double angle diagonal bracing members " Capacity-demand ratio is 0.709. Notes 4 through 8 are for corroded members with reduced strength. Corrosion was classified as minor or major depending on the extent of corrosion observed in the member. More frequent painting is recommended to protect structural members from further corrosion. Minor corrosion is estimated to reduce the strength of the m ember by 5 percent whereas major corrosion is estimated to result in a 10 percent reduction in strength of the members. Note 9 pertains to strength reduction due to load attachments by both welded and bolted connections to the columns. The members reported in Note 9 were not damaged, but a 5 percent strength reduction was considered. 4. All steel members in the hangars open area " Minor corrosion " 5 percent strength reduction " since capacity-demand ratio is less than 0.5, paint only as recommended in General Retrofit Notes. 5. Column N-S ? (8-H-Si, length: 426 in.) " Major corrosion at the columns base " 10 percent strength reduction " analysis revealed that this column has a significant margin of safety; thus, paint only as recommended in General Retrofit Notes. 6. Column P-S ? (124-25, length: 426 in.) " Major corrosion at the columns base " 10 percent strength reduction " analysis revealed that this column has a significant margin of safety; thus, paint only as recommended in General Retrofit Notes. 7. Column A-S ? (8-H-31, length: 426 in.) " Minor corrosion at the columns base " 5 percent strength reduction " Since capacity-demand ratio is less than 0.5 as a result of the analysis, paint only as recommended in General Retrofit Notes. 8. Column AA-4 ? (12-1-25, length: 426 in.) " Minor corrosion of the column at the height of the concrete wall, approximately 5 ft above the floor " 5 percent strength reduction " Analysis revealed that this column has a significant margin of safety; thus, paint only as recommended in General Retrofit Notes. 9. There are many attachments by both welds and bolted connections to the columns of lines 2 and 4. The members do not look damaged, but a 5 percent strength reduction was considered. Since capacity-demand ratio is 0.364, no action is recommended for this note. General Retrofit Notes: 1.
