You may use a support displacement load. You can find the details on this load type in the STAAD.Pro Help section Technical Reference of STAAD Commands > TR.32 Loading Specifications > TR.32.8 Support Joint Displacement Specification. 
 A discussion on the similar topic can be found here: https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/113633/enforced-support

If the model includes plates, you have to use the "ENFORCED" and "ENFORCED BUT" type of supports to apply the support displacement load. Please, find the attached model where support displacement loading was used together with PLATE MAT. In the model the load case 3 is followed by a PERFORM ANALYSIS and CHANGE commands and subsequently support specifications are changed to PLATE MAT. Support displacement example.std
