the new local status of the brotherhood in 1956, gender references were deliberately excluded from the text, making the house officially coeducational before the college itself. The vote in 1973 formally confirmed the membership policy. Unlike other coeducational Greek houses, members of Phi Tau have continued to refer to one another as "brothers", regardless of their gender. Phi Tau is the only coeducational Greek house at Dartmouth that has always had female members since first admitting them, and was the first fraternity at the College to add sexual preference to its non-discrimination clause. In the 1980s, the Phi Tau residence began to face serious structural problems after the removal of a porch on the south side of the building. The walls of the building were constructed out of brick. Presented with different loads and stresses, the north wall began to bulge outward by nearly half a meter, and was literally threatening to explode. Large steel plates were placed on the outside of the building and steel tie rods were threaded through the building between the ground and second floor to pull the plates together and force the exterior walls to straighten. A new tradition began of articles in alumni newsletters proclaiming, "The north wall is still standing!" The College introduced undergraduate societies to campus in 1993, as a residential and social alternative to Greek organizations. Similar to the Greek houses in many respects, undergraduate societies were required to have open, coeducational membership policies. Panarchy, a coeducational fraternity with a 97-year history at Dartmouth, voted to change its status to an undergraduate society and was joined the following year by a newly formed society, called Amarna. Phi Tau chose to remain a Greek house. In 1999, the College administration announced a "Residential and Social Life Initiative" to improve campus life. Speculation that all Greek houses at Dartmouth College might be forced to open admissions to anyone who wanted to join drew attention to Phi Tau's status as an already coeducational institution, but one that still held to Greek traditions. Then house president Virginia DeJesus-Rueff, class of 2000, defended Phi Tau's policy of self-selection. In 2000, Dartmouth College unveiled a new master plan for the north side of the campus. The development plan called for the creation of a green on the northern side of the libraries in the center of campus, and anticipated the use of a portion of the property
