建筑工程作业代写 Assuming a 40 psf wind suction, calculate the magnitude of forces and reactions based upon the load path shown above.

Curtain Wall and Cladding 建筑工程作业代写

1.Seek out, on foot, an extensive glass wall or roof enclosure on a local building. Assess the system and its apparent condition, in Word, Line and Number (3 languages).

Page 1 shall be a written narrative.

o Discuss materials, from glass cladding to joints to structure

o Note manufacturer if possible

Page 2 shall include up to 4 photographs.
Page 3 shall include two hand sketches.

o One big picture, meaning enough to represent the load path (a full bay and floor level) 建筑工程作业代写

o The second, a detail, which could be a connection point of glass to subframe, or a key cross section.

Page 4 shall be mathematical calculations.

o Provide load path diagrams of how wind pressure is distributed from glass to subframe to building frame;

o Do (1) of the following:

 Calculate appropriate wind load for the structure using ASCE-7.

 Assuming a 40 psf wind suction, calculate the magnitude of forces and reactions based upon the load path shown above.

2.For the attached sketches for stone cladding: 建筑工程作业代写

a.Given:

i.Stone density 170 pcf

ii.Wind Pressures:

1.40 psf toward wall

2.20 psf suction

iii. Wind pressure exceed seismic load, therefore neglect seismic considerations

iv.Joints are constructed from flexible rubber gaskets and therefore, no load is transferred between the stone cladding panels

v.Gravity support bent plates are stainless steel with

1.Fy = 30 ksi; with an allowable bending stress in weak axis = 0.75 Fy.

2.E same as typical structural steel

b.Find:

i.Reactions at gravity supports and lateral ties from Gravity load of stone (use unfactored loads). At gravity support calculate the shear and pullout value in the anchor.

1.Consider first a free-body diagram of the stone itself, and its support on the gravity clip and stability from the lateral ties. 建筑工程作业代写

2.Then analyze the gravity clip to calculate the shear and pullout value in the anchors.

ii.Combined reactions at gravity supports and lateral ties from Gravity and Wind Suction (use unfactored loads). As above, at gravity support calculate the shear and pullout value in the anchor.

iii. Required plate thickness for gravity support for strength and deflection. Assume a vertical deflection limit of a maximum of 1/8”.Reading Assignment:
