I have solved the problem why the circuit was not working in the Tina simulation. The triac shown in the circuit had a gate current of 50 ma. The .1uf capacitor could not provide that current. I have substituted a 2N6349A Triac which has a gate current of only 6ma. Now the circuit works just fine.
Tina has many triac and diac models. Ltspice has no such models. I couldn't even import any 3rd party triac models into it. Anybody looking for triac simulations switch to Texas Instruments Tina.
