    Concrete Slabs - how should they be joined

    IF THE STRUCTURES ARE TOTALLY INDEPENDENT, IT IS NOT NECESSARY TO JOIN THE FOIUNDATIONS. IF THE STRUCTURES ARE ATTACHED AND DEPENDENT ON THE FOUNDATIONS PERFORMING AS ONE, YOU WILL HAVE TO LIMIT SETTLEMENT BETWEEN THE STRUCTURES AND DOWEL THE STRUCTURES TOGETHER. THE GOAL OF GAINING TOTAL...

    New AISC Combined Spec

    MORE COMPLEX METHODS MAY MAKE BETTER STRUCTURES, BUT LEAVE MORE ROOM FOR ERROR, HENCE MORE POINTS TO ARGUE IN COURT. ADDITIONALLY THE MORE COMPLEX THE METHOD MAKE THE BETTER THE TEACHING OPPORTUNITIES. THE REALLY BASIC QUESTION IS DO ANY OF THESE COMPLEXITIES MAKE SAFER STRUCTURES. CAN ANY...

    New AISC Combined Spec

    I USE LFRD WHEN DESIGNING STRUCTURES THAT ARE PROTO TYPICAL FOR MANY LOCATIONS. LFRD APPEARS TO PROVIDE SLIGHTLY LESS COSTLY STRUCTURES. HOWEVER I DO NOT PREFER IT AS A MATTER OF COURSE.

    Soil Bearing Capacity from N-values of SPT for Design Purposes

    YOU NEED TO CONTACT A GEOTECH THAT DID THE TESTING OF THE SOIL. THE N VALUES ARE GOOD AS A RULE OF THUMB, HOWEVER SOME SOILS ARE SENSATIVE TO MOISTURE CHANGES AND OTHER SOILS ARE SENSITIVE TO RE MOLDING.  CAUTION IS THE WATCH WORD

    Grade Beam Design for Buildings

    THE POST-TENSIONING INSTITUTE HAS A LINE LOAD ANALYSIS FOR GRADE BEAMS IN THE SLAB ON GROUND PROGRAM. PERSONALLY, FOR THE LAST FORTY YEARS I'VE BEEN DESIGNING THEM LIKE A WALL FOOTING. THE PROOF IS IN THE PUDDING. SO FAR SO GOOD.
