COLLAPSE OF TEXAS TOWER NO. 4 43 



turally in bracing the legs, so that you still have a clear gain. There 

 are two different conceptions used here. I do not know how far you 

 want to go into it. But in this case you have essentially what we call 

 a rigid frame which acts to resist lateral forces merely by the moments 

 created in the elements that you see — the legs. In this case, we have — 

 by means of the bracing — built up a truss plane which resists the 

 lateral forces as a unit, which is quite different in principle in the two 

 structures. And, therefore, the mere fact that these braces do pick 

 up more resistance from the waves, which is unavoidable, you have to 



have them in the deep water because of the larger structural 



Senator Stennis. Excuse me just a moment. I must go. Will you 



fentlemen excuse me now, and just proceed as you wish. Senator 

 ymington will preside. I hope it is all right with the conunittee — 

 2:30? 



Senator Saltonstall. Mr. Chairman, I must leave too ; right now. 



Senator Stennis. Wlien we do recess, it will be until 2 :30. I hope 

 you can come back. 



Senator Saltonstall. Senator Symington, may I ask one more 

 question ? 



Now, Mr. Anderson, was the weight of the superstructure on tower 

 4 any different than on towers 2 and 3 because of the difference in the 

 underpinning ? 



Mr. Anderson. There was no material difference in weight. 



Senator Saltonstall. So that from your point of view, in design- 

 ing the superstructure, you relied on the Rutledge firm to design the 

 underpinning from the superstructure down sufficiently strong to take 

 the same design that you put on for towers 2 and 3. 



Mr. Anderson. That is correct. 



Senator Saltonstall. Mr. Chairman, that is all I have. 



Senator Symington. Thank you. As I understand, when you were 

 approached first by Mr. Seddon, Mr. Anderson, Moran Proctor would 

 do the submarine foundation work and you were going to do the su- 

 perstructure work ; is that correct ? 



Mr. Anderson. That is correct ; yes, sir. 



Senator Symington. And later on there was a special conference 

 on July 22, 1954. Wliy do you call it a special conference ? 



Mr. Anderson. Well 



Senator Symington. What was unusual about the conference ? 



Mr. Anderson. There was nothing unusual. There were a whole 

 series of conferences of this type. This particular one was held in 

 New York. 



Senator Symington. Well, I wondered why you said "special." 



Mr. Anderson. Well, that is the way the minutes were written. It 

 is called a special conference. I do not think it was particularly signi- 

 ficant. 



Senator Symington. At this conference Commander Albers appar- 

 ently told you that you were going to get a lot less of the work than 

 you thought you were going to get when you asked the Kutledge firm 

 to come in ; is that correct ? 



Mr. Anderson. That is what the division of work resulted in ; yes. 



Senator Symington. And that is when you first knew about it ? " 



Mr. Anderson. That is correct. 



Senator Symington. Why do you think that was done ?
