I WANT TO FIT A SCISSORS SYSTEM ROOF ON A BUILDING WITH REINFORCED CONCRETE COLUMNS+FLOORING. IT IS A SITUATION THAT CANNOT BE A DEPLOYMENT PROBLEM. I CANNOT ANALYZE REINFORCED CONCRETE AND THIS ROOF SYSTEM AT THE SAME TIME. THE SYSTEM SAYS IT CAN'T SOLVE AND SHUT UP.. - I FURTHER I WANT TO ANCHORAGE THESE SCISSORS TO THE ROOF ON THE COLUMN HOW CAN I SHOW THIS. IS IT POSSIBLE FOR ONE SIDE TO HAVE A SLIDING JOINT IN THIS ANCHOR?
