A rafter reinforcement bracket apparatus for securing rafters to strengthen a wood frame roof includes a bendable strap configured to conform to a rafter bottom side of a pair of opposing rafters and a beam between the pair of rafters. A left and right bracket are coupled to a strap top side adjacent a strap front edge and a strap back edge, respectively. Each has a perpendicular portion extending perpendicularly from the strap and an upper portion extending perpendicularly from the perpendicular portion and lying in a plane parallel to a plane of the strap. Each of the strap, the left bracket, and the right bracket has a plurality of mounting holes extending therethrough. Each of the mounting holes is configured to receive a fastener to fix the apparatus to the pair of opposing rafters and the beam.

The present invention is a method for accessing a model, wherein the model incorporates a plurality of roof truss assemblies, wherein the assemblies are comprised of a plurality of members; detecting at least one interface between at least two roof truss assemblies, and wherein the interface type is detected; recording, by at least one processors, a interface type, wherein a set of required values based on the interface type are identified; calculating a set of actual values associated with the interface; comparing if the set of actual values is within the required values; identifying a modification to at least one roof truss assembly involved in the interface; incorporating the modification into the model; and analyzing the model for newly created interfaces between a set of members of the model.

A large-angle sloping roof steel structure connected to a main body structure, including: an intermediate platform, inclined main supporting steel columns circumferentially connected at four corners of the intermediate platform, constructing steel columns and wind-proof surrounding beam connected between top ends of the inclined main supporting steel columns, where roof purlin are connected between the adjacent inclined main supporting steel columns at intervals. The invention provides a top-down inverted construction method for a large-angle sloping roof with a steel structure as the main structural form. By using the method, the operation safety of an inclined main stressed vertical member during the installation process can be ensured, and the investment of supporting measures is reduced by preferentially installing the intermediate platform, thus effectively ensuring the installation progress, quality and safety of the sloping roof steel structure. The present invention can be widely applied to sloping roof construction.
