The element uses hinges (passed as // object pointers) at the element ends. The middle section // is analyzed elastically, while the hinge ends return // a section flexibility sampled at their middle points. The element // calculates a frame (6x6) stiffness matrix from this info. // #ifndef BeamWithHinges2d_h #define BeamWithHinges2d_h #include <Element.h> #include <Matrix.h> #include <Vector.h> #include <ID.h> #include <Node.h> #include <Channel.h> #include <FEM_ObjectBroker.h> #include <SectionForceDeformation.h> #include <CrdTransf2d.h> #include <Response.h> #include <Renderer.h> class BeamWithHinges2d: public Element { public: BeamWithHinges2d (); BeamWithHinges2d (int tag, int nodeI, int nodeJ, double E, double I, double A, double G, double alpha, SectionForceDeformation &sectionRefI, double hingeIlen, SectionForceDeformation &sectionRefJ, double hingeJlen, CrdTransf2d &coordTrans, double shearL = 1.0, double massDensPerUnitLength = 0.0, int max = 1, double tol = 1.0e-10); BeamWithHinges2d (int tag, int nodeI, int nodeJ, double E, double I, double A, double G, double alpha, SectionForceDeformation &sectionRefI, double hingeIlen, SectionForceDeformation &sectionRefJ, double hingeJlen, CrdTransf2d &coordTrans, const Vector &distLoad, double shearL = 1.0, double massDensPerUnitLength = 0.0, int max = 1, double tol = 1.0e-10); ~BeamWithHinges2d(); int getNumExternalNodes (void) const; const ID &getExternalNodes (void); int getNumDOF (void); void setDomain (Domain *theDomain); int commitState (void); int revertToLastCommit (void); int revertToStart (void); const Matrix &getTangentStiff (void); const Matrix &getSecantStiff (void); const Matrix &getDamp (void); const Matrix &getMass (void); void zeroLoad (void); int addLoad (const Vector &moreLoad); int addInertiaLoadToUnbalance(const Vector &accel); const Vector &getResistingForce (void); const Vector &getResistingForceIncInertia (void); int sendSelf (int commitTag, Channel &theChannel); int recvSelf (int commitTag, Channel &theChannel, FEM_ObjectBroker &theBroker); Response *setResponse (char **argv, int argc, Information &info); int getResponse (int responseID, Information &info); int setParameter (char **argv, int argc, Information &info); int updateParameter (int parameterID, Information &info); void Print (ostream &s, int flag = 0); int displaySelf(Renderer &theViewer, int displayMode, float fact); protected: private: void setNodePtrs (Domain *theDomain); void getGlobalDispls (Vector &dg); void getGlobalAccels (Vector &ag); void setStiffMatrix (void); void setMass (void); CrdTransf2d *theCoordTransf; void getForceInterpMatrix (Matrix &b, double x, const ID &c, int &shearKey); void getDistrLoadInterpMatrix (Matrix &bp, double x, const ID &c); void setHinges (void); void setElasticFlex (void); double E, I, A, G, alpha, L; double massDens; double hingeIlen, hingeJlen; ID connectedExternalNodes; Node *node1Ptr, *node2Ptr; SectionForceDeformation *sectionI, *sectionJ; Matrix K; Matrix m; Matrix d; Matrix fElastic; Matrix vElastic; Matrix b1, bp1; Matrix b3, bp3; Matrix fs1, fs3; Vector sr1, sr3; Vector e1, e3; Vector UePrev; Vector P; Vector Pinert; Matrix kb; Vector q; Vector load; Vector prevDistrLoad; Vector distrLoadCommit; Vector UeCommit; Matrix kbCommit; Vector qCommit; bool initialFlag; double shearLength; int shearIkey, shearJkey; int maxIter; double tolerance; }; #endif ÿ
