The example belowd is a simple tutorial to learn SACS. Cantilever with properties W24×104, the structure model can be seen below. Perform a UC member detail and moment diagram using SACS program!



1. CREATE NEW MODEL

Interactive Model > Model > Create New Model > OK

New Structure > None > OK

2. CREATE JOINT

Joint > Add > Absolute > Input (joint Name = 1, x = 0, y = 0, z = 0, fixity = 111111)

Joint > Add > Relative > Input ( joint name = 2, x = 10, y = 0, z = 0, fixity = leave blank, reference joint = 1)

3. CREATE MEMBER

Member > Add > Input (joint 1 = 1, joint 2 = 2, group label = IWF). Note : you can click the joint to chose joint member.

4. DEFINE SECTION PROPERTIES

Property > Member Group > Define (select group IWF)

Click button on section label (the blank button near the section label)

Select W24×104 (on the section list)

5. DEFINE LOAD

Load > Member > Click Member > Click Apply

Member Load > Input (load condition = DEAD, load ID = DL, load type = distributed) > Add

Member Distributed > Input (load type = force, coordinate system = global, direction = z, inital value = -10, distance to beginning = 0, load length = leave blank, load ID = DL)

Sum of Forces Report > Save

6. SAVE FILE

File > Save As > Check List Seastate and Model (to combined between seastate and model) > OK

File Name Format for SACS : SACINP.<FILE NAME> (exmp : SACINP.CANTILEVER) Click OK

7. RUN FILE

Click Run File Wizard > Choose Statik (to perform statik analysis) > Start Wizard > Choose SACS Input file (SACINP.CANTILEVER)
