Phase One Test Summaries 

Task Number: 5.4.2 

Task Title: Development and Evaluation of Analytical Tools for Benchmark and Analytical Investigations 

Topical Area: Topical Investigations of Connection Performance 

Subcontractor: Helmut Krawinkler 
Stanford University 

Task Summary: 

    The specific objectives of this task are to: 

1. Define local and global response parameters of interest in the nonlinear analysis of steel moment frame structures; 

2. Devise an electronic data base for acquisition, manipulation and statistical interpretation of information on these response parameters obtained from a wide variety of analyses conducted throughout the Phase 2 project; 

3. Assess a compilation of computer program capabilities suitable for analysis of complete buildings and connections; 

4. Develop a "bench mark frame" that can be used to assess the accuracy, efficiency and practicability of available computer programs; 

5. Use the "benchmark frame" to assess a commonly available computer program, including a element model capable of simulating beam fracture, and to develop software to transfer response data from this program into the prescribed format needed for the Phase 2 project's analysis database.
