# X-Braced Bent Analysis for Lateral Loads (1 Story Buildings)

For 1-Story Bent

Assuming Fully Braced, Tension-Only System

#### Forces and Reactions:

**Member Force Sign Convention:**

+ = Compression

- = Tension

**Vertical Reaction Sign Convention:**

Upward = Compression

Downward = Tension (Uplift)

#### Input Data for Drift Analysis:

Member Data | |||
---|---|---|---|

Designation | Length | Area | |

(ft.) | (in.^2) | ||

Left Col. | LC1 | ||

Right Col. | RC1 | ||

Beam | HB1 | ||

Brace | DB1 | ||

Mod. of Elasticity, E = | ksi |

Nomenclature:

LC = Left Column Segment

RC = Right Column Segment

HB = Horizontal Beam

DB = Diagonal Brace

Note: Column segments, beams,and braces are numbered from bottom to top, same as stories.

#### Results:

Note: Results are for joints at left side of bent, with all members (segments) assumed pinned at both ends.
