WMATA's design and construction standards, to which the SSTC was supposed to have been designed and constructed, require expansion/contraction joints be installed no more than 100 feet apart.
The 315 ft. by 580 ft. SSTC has NONE.
This is what happens when you don't follow instructions:

The "repairs" that are now being done to the SSTC (latex concrete overlay and exterior reinforcement for under-designed beams) won't fix the source of the cracking: the SSTC's total lack of expansion/contraction joints. The SSTC will continue to crack.
The public paid more than retail ($130+ million; 53% federal funding, 11% state and 36% county) for a brand new, unflawed transit center; the public doesn't deserve this lemon.
